Heat safety tips for July 4th and beyond

By Dan Stillman

* Heat set to return: Full Forecast | Beach Forecast | NatCast *

The European weather model (ECMWF) shows an intense heat wave for much of the eastern U.S. Sunday into next week. The above graphic shows predicted temperatures for Tuesday at an altitude of about 5,000 feet. The dark red over the D.C. area represents upper 70s, which could translate to surface highs near 100.

Another prolonged stretch of what looks to be highs in the mid-90s and higher is set to begin Sunday (July 4th) and last for much, if not all, of next week. While it may not be as epic as the heat waves of the 1930s, as CWG's Kevin Ambrose recently wrote about, this next round of heat is likely to keep firefighters and paramedics as busy as the first.

Here are some tips to keep you, your family and friends out of harm's way this holiday weekend and beyond...

From Alert DC...


In preparation of the July 4, 2010 weekend the DC Homeland Security and Emergency Management Agency advises all residents and visitors to take note of the following precautions:

Avoid Heat Exhaustion/Heat Stroke: Understand the symptoms of heat illnesses. These include dizziness, extreme sweating, muscle cramps, tiredness, weakness, and cold or clammy skin. Symptoms that are more serious include nausea, vomiting, and fainting.

Stay Hydrated:
o Limit your intake of beverages that contain high levels of alcohol or large amounts of sugar or caffeine-these actually dehydrate you cause you to lose more body fluid. Also, avoid very cold drinks, as they can cause stomach cramps.
o Drink a lot of water!

Stay Cool: It is going to be hot. The national weather service is predicting the weather to be sunny and hot with a high of 97 °F
o Wear a hat & lightweight, light-colored, loose-fitting clothing.
o Try to rest often in shady areas.
o Protect yourself from the sun by wearing a wide-brimmed hat (also keeps you cooler) and sunglasses and by putting on sunscreen of SPF 15 or higher (the most effective products say "broad spectrum" or "UVA/UVB protection" on their labels).
o Seek shade when possible and remember that the sun's UV rays are strongest between 10 a.m. and 4 p.m.

Pay Special Attention to Others: Although any one at any time can suffer from heat-related illness, some people are at greater risk than others are.
• Monitor those at High Risk:
o Infants and young children
o People aged 65 or older
o People who have a mental illness
o Those who are physically ill, especially with heart disease or high blood pressure

Do not leave infants, children, or pets in a parked car.

In case of an emergency, dial 911. For general questions, or to report a problem, call the Mayor's Citywide Call Center at 311.

It's a good idea to drink plenty of water before it gets scorching hot -- by the time you feel thirsty, you're already dehyrdrated. Consistency is the key year-round.

I would consider trading with you guys. It is currently 55 degrees, heading for a high of 68 degrees today. The local observation is calling it cloudy, but looking out my office window it appears to be completely overcast to me.

It is downright cold and dreary here. No sunshine at all. Anyone want to trade?

@Mr. Q. if you're in San Francisco, yeah, I'm ready for some 50s-60s. If you're in Juneau, maybe not.

Not San Francisco. Not Juneau. Oregon, Portland metro area. You need to be a fan of rain to live here. Bring your snorkel. :)

My advice, get outside and enjoy the weather today and tomorrow while it lasts! Sunday will be downright uncomfortable and dangerous...especially if you're in a crowd of thousands of people on the Mall.

Hang in there, Mr. Q. Portland should see temps close to 90 by Tues/Wed, while DC
will be in the upper 90's. For both that's just about 10 deg warmer than "normal" (average).
