The National Weather Service issued a “Heat Advisory” for the northwest on Tuesday (July 6), as the summer season gets “switched on,” with temps predicted to hit highs around 90 degrees or so toward the end of the week.

First, the weather service’s advisory in its full glory:

Statement as of 3:23 PM PDT on July 06, 2010

… The first stretch of hot weather is expected across western Washington this week…

The cool and moist onshore flow pattern which dominated western Washington weather through the Fourth of July has come to an end this week… as a strong upper level ridge and offshore develop over the area. Offshore flow will increase tonight and Wednesday helping maximum temperatures to rise into the 80s to mid 90s the next few days.

Latest computer models indicate that the upper level ridge will weaken this weekend and onshore flow will return. This is the more typical onshore flow we see during the Summer that helps to moderate the warmest weather patterns. Although temperatures will cool down a little this weekend… they will remain warmer than normal.

Temperatures in the 80s to mid 90s can cause some heat related health problems even in western Washington. As temperatures climb into the 90s… sunstroke… heat cramps and heat exhaustion are possible with prolonged exposure and/or physical activity. This is especially true for the elderly. Some precautions that will reduce the risk of heat related illness include but are not limited to… reducing strenuous activity… wear lightweight and light colored clothing… and drink plenty of water or other non-alcoholic fluids. Also… never leave children or pets unattended in vehicles during hot weather.

***The following are the record high temperatures and year of occurrence for select locations. Refer to the forecast for the expected high temperatures on these dates.***

Wednesday /Thursday /Friday

Sea-tac 88 (1953) 87 (1985,52) 91 (1985)

Olympia 95 (1953) 94 (1952) 95 (1985)

Bellingham 88 (1953) 85 (1952) 85 (1979,52)

Quillayute 80 (1996) 82 (1968) 85 (2007)

Hoquium 81 (1996) 87 (1956) 83 (2002)

Sandpoint 82 (1996) 82 (2006) 81 (2003)

And now, some ways to beat the heat in Des Moines, along with some common sense tips:

1. If you don’t have air conditioning, find a cool place to hang out. Beaches are almost always cooler (and FREE), plus dipping your toes in Puget Sound will most definitely cool you off; all King County Library branches have air conditioning, as does the Senior Center and numerous other publicly-accessible buildings around the area.

2. Red Cross Safety Tips:

With temperatures expected to rise this week, the American Red Cross encourages individuals and families to take the necessary precautions. The very young and the elderly are especially vulnerable to the heat, so it is important that families and friends check on them regularly.People with chronic health issues are also at greater risk and need to take special care to stay healthy in the heat.

Prevent Heat-Related Illness:

• Dress for the heat. Wear lightweight, light-colored clothing (light colors reflect away some of the sun’s energy) and plenty of sunscreen. Wear a hat or use an umbrella to help shield you from the sun.
• Carry water or juice and drink frequently, even if you do not feel thirsty. Avoid alcohol and caffeine, which dehydrate the body. Make sure to check on youth and elderly to make sure they have enough fluids.
• Eat small meals and eat more often. Avoid foods that are high in protein, which increases metabolic heat.
• Avoid using salt tablets unless directed by a physician.
• Avoid strenuous activity. If you must do something physically demanding, try to do it during the coolest part of the day, which is usually between 4:00 and 7:00 a.m. Take regular breaks to cool off.
• Stay indoors as much as possible.
• Be vigilant about water safety if headed to a pool or beach. Never leave a child unattended near water and keep lifesaving gear handy.
• Watch for signs of life-threatening heat stroke. The person’s temperature control system, which produces sweating to cool the body, stops working. The body temperature can rise so high that brain damage and death may result if the body is not cooled quickly.
• Signals of heat stroke include hot, red, and usually dry skin, changes in consciousness, rapid, weak pulse and rapid, shallow breathing.
• If you or someone you know experience symptoms, call 9-1-1 or your local EMS number. Move the person to a cooler place. Quickly cool the body by wrapping wet sheets around the body and fan it. If you have ice packs or cold packs, place them on each of the victim’s wrists and ankles, in the armpits and on the neck to cool the large blood vessels. Watch for signals of breathing problems and make sure the airway is clear. Keep the person lying down.
• Don’t forget to protect your pets.
• Limit exercise to the coolest part of the day, typically early in the morning. Even in the coolest part of the day, watch for signs of trouble. Glassy eyes and frantic panting indicate a dog needs help.
• Make sure your pet has constant access to shade and an endless supply of cool, clean water.
• Never leave a pet in a car – even for a few minutes.
• Be vigilant for signs of heat stroke, which is deadly for pets. Symptoms include sluggish and non-responsive demeanor, bright red and/or dry tongue and gums, vomiting or diarrhea and/or unusual breathing patter, heavy panting, or high heart rate. If your pet displays these symptoms, get emergency medical attention.

The National Weather Service issued a “High Wind Watch” advisory Thursday afternoon (April 1), and unlike some of our earlier stories, this one’s no joke – expect wind speeds between 35 and 55 MPH beginning around 10am Friday, April 2nd.

This means that there could be downed trees, power outages, road hazards, and of course, messy hair aplenty.

It also means snow and high winds in the mountains, along with treacherous pass conditions, so be careful if you’re traveling anywhere for Easter weekend.

Here’s the language the weatherfolk are using:

…High wind watch remains in effect for the greater Puget Sound region…east Puget Sound lowlands…and the lower Chehalis valley from Friday morning through Friday afternoon…

A high wind watch remains in effect from Friday morning through friday afternoon. * very strong…possibly damaging…south winds may develop along and behind a cold front on Friday…over portions of interior Western Washington.

There is still some uncertainty as to the exact track and depth of the associated surface low moving near or just north of washington. At this time…the most likely scenario would generate south winds of 25 to 35 mph with gusts up to 55 mph.

However…if the surface low deepens more than expected…wind speeds could reach close to high wind criteria. Therefore the high wind watch remains in effect until details are more certain. * the very strong winds could result in some power outages across portions of western washington friday afternoon and evening due to power lines being damaged by tree limbs. Some of the regions trees have begun to leaf out already…which could add to the potential for wind damage to occur. Rain soaked ground could allow trees to easily topple or become uprooted.

Precautionary/preparedness actions… A high wind watch means conditions are favorable for damaging winds. High winds can topple trees…down power lines…and damage some structures.

• Confidence is high that strong winds and heavy snow will affect the mountains.
• Confidence is high that damaging winds will affect the Washington Coast and North Interior
• Confidence is only moderate that damaging winds will affect the Central Puget Sound area

A strong spring storm system will develop offshore and rapidly move through Western Washington Friday

• Strong and damaging winds are expected, especially along the coast and in the northern interior of Western Washington
• Trees have begun to leaf out, so there is a greater likelihood of downed limbs and trees
• Heavy mountain snow of 1 to 3 feet is expected in the Cascades and Olympics above 3000 feet.
• Increased avalanche hazards in the Cascades and Olympics
• Heavy rainfall at lower elevations of the Southern Olympics will cause rises on the Skokomish river, though flooding is not expected at this time. Other rivers will not flood.

Bulk of Puget Sound area and Southwest Interior: S to SW 35 (with) Gusts of 55 mph beginning 10 AM PDT

The National Weather Service issued an unusual Advisory Monday (Jan. 18th) – this one for a “minor tidal overflow” that will be in effect for Puget Sound Tuesday morning and possibly again Wednesday morning.

According to the report, “very high astronomical tides combined with lower than normal atmospheric pressures” as well as high winds may cause some flooding.

So, if you live near the shoreline and your street/yard/area has a tendency to flood, you might want to put out some sandbags just in case.

Here’s the actual advisory:

… Coastal Flood Advisory for minor tidal overflow is in effect for Puget Sound and the north interior from 5 am to 11 am PST Tuesday…

The National Weather Service in Seattle has issued a coastal Flood Advisory for minor tidal overflow from Puget Sound to the north interior… which is in effect from 5 am to 11 am PST Tuesday.

Minor tidal overflow may occur along some of the shorelines and nearby low-lying areas around Puget Sound and the north interior Tuesday morning… around the time of high tide. Minor tidal overflow is caused by very high astronomical tides combined with lower than normal atmospheric pressures. The Table below shows time of high tide for areas around Puget Sound… along with the normal tide table value and the expected total tide.

Time of tide table expected expected location high tide value anomaly total tide

• Seattle 7:30 am 12.2 ft 1.6 ft 13.8 ft
• Port Townsend 7:06 am 9.1 ft 1.8 ft 10.9 ft
• Bellingham 8:12 am 9.6 ft 1.9 ft 11.5 ft

Minor tidal overflow problems usually begin at 13.5 feet around Seattle and 11.5 feet around Bellingham… and the current forecasts for those areas just meet or exceed those levels. In addition… the atmospheric pressure could be a little lower than forecast… and local winds may cause water to pile up along shorelines more than expected… possibly higher than the expected total tide values. Southeast winds 20 to 30 knots are forecast over the northern inland waters Tuesday morning as another deep low pressure system moves northward offshore. Winds over the waters of Puget Sound are expected to be south 10 to 20 knots Tuesday morning.

Another very high astronomical tide will occur Wednesday morning. The forecast tides for Wednesday morning are slightly lower than for Tuesday… but computer model forecasts indicate the anomaly will still be large enough so that minor tidal overflow problems remain a possibility.

Precautionary/preparedness actions…

Minor tidal over flow can cause local flooding along shorelines and nearby low-lying areas.

The National Weather Service issued a “Special Weather Statement” at 4:30pm Thursday (Nov. 12th), warning of a “vigorous cold front” hitting the area Friday morning, bringing rain, wind and snow to the mountains.

Could this be the first breath of ol’ man winter?

Here’s the statement:

… Active weather day expected Friday…

A vigorous cold front will pass southeast across western Washington Friday morning… bringing Rain… Mountain snows… locally windy conditions and possibly snow showers to parts of The Lowlands.

South winds in advance of the front will increase late tonight into early Friday morning… mainly along the coast and parts of the northwest interior including the Admiralty Inlet region. Wind speeds in those areas are expected to reach 20 to 30 mph with a few gusts to 45 mph… mainly in and around the Island County area. After the front passes… winds will become west to southwest down the Strait of Juan de Fuca and across the northwest interior before diminishing through the afternoon. While below Wind Advisory criteria… wind of this strength could blow down a few tree limbs here and there with isolated power outages.

Colder air will surge in behind the front and lower already low snow levels across the region. During the morning hours ahead of the front the snow level will be around 1500 to 2000 feet. The snow level will then gradually drop through the day to around 500 feet by evening. This means some of the highest hills around the region could see a few snow showers late Friday into Friday evening. However… outside of the mountains or the immediate Cascade foothills… little to no snow accumulation is expected.

Dry and tranquil weather will return to the region late Friday night into Saturday.

The National Weather Service issued a “Special Weather Statement” Tuesday, Nov. 3rd at 4:57pm, warning of “very strong” winds and rain hitting the area Thursday (Nov. 5th) with gusts possibly as high as 50mph.

Here’s the warning in all its glory:

Statement as of 4:57 PM PST on November 03, 2009

… Windy conditions for the mountains… coast… and northern interior Thursday…

A strong Pacific frontal system will impact western Washington on Thursday. Breezy southeasterly winds on Wednesday night will become south-southwest on Thursday for the north interior and coast increasing to 20 to 30 mph with gust as high as 50 mph.

Winds just above the surface will be very strong on Thursday. Ridgetop winds for the Olympics and lower south facing slopes will range from 45 to 65 mph with higher gusts possible. Ridgetop winds along the southern slopes of the Cascades will also be windy… with sustained winds up to 50 mph possible. The strong winds will also be accompanied by heavy rains… combining for dangerous conditions in the mountains.

So…considered yourself warned – hold on to your hats and batten down your boats Des Moinesians!

The National Weather Service has issued a “Special Weather Statement” alerting us all that, despite the recent sunny and mild weather, the rain is a-comin’ back, starting Tuesday (Oct. 13th), so be sure to take heed an move all that crap in your yard and driveway back inside.

Here’s the statement, which was published at 4:44pm Sunday Oct. 11th:

Statement as of 4:44 PM PDT on October 11, 2009

… A series of Pacific storms will affect western Washington this week…

Columbus day will be a transition day from the recent cool and dry spell to an active… wet pattern. Look for a series of Pacific storms to affect the area starting Tuesday. The Tuesday system is expected to bring windy conditions to the coast and Cascade foothills as well as precipitation to the entire area. Chilly…east winds in the Cascade passes will mean that the precipitation will begin as snow or a rain and snow mix. However… significant snowfall amounts are unlikely.

Unsettled… wet conditions will persist on Wednesday as the region remains under the influence of a large area of low pressure over
the eastern Pacific. A much wetter system may affect the area during the latter part of the week.

The National Weather Service issued a “Special Weather Statement” late Thursday afternoon (July 23rd) warning about a heat wave that will begin this weekend and last into next week, with projected highs in the 85-95 degree range.

Here’s the official warning:

… Hot weather beginning this weekend and lasting into next week…

The hottest weather of the year is likely to occur this weekend and early next week. High temperatures will be in the 85 to 95 range. Overnight lows will be in the 60s. All areas of western Washington could be affected.

The first really hot day will be Saturday or Sunday. The hottest days look like Sunday through Tuesday. At this time models predict the hot weather could last into Thursday or beyond.

Unlike many previous hot spells… this one could also affect the coast and other places near the water. Also it is rare to have many hot days in a row in western Washington… but this heat wave could last several days.

Western Washington is having a dry Summer… and no rain is in the forecast for the next week or so. Fire danger will increase during the hot weather. There is also a risk of air stagnation during this period.

The National Weather Service will issue more statements about this event over the coming days.

And according to meteorologist Cliff Mass:

“I took a look at the long-range forecasts and was shocked.

The temperature climbs through the weekend…into the lower 90s on Sunday and mid 90s at least on Monday and Tuesday.

Too far out to be sure now….but be ready for real heat.”

BTW, Cliff also adds that:

“2009 is the driest 20 May-19 Jul period on record using the combined SeaTac/downtown observations”

So…have a great weekend, but stay cool, slathered up, and be sure to check in on elderly neighbors/relatives and drink plenty of water!
