Heat Advisory for Tuolumne County

According to the National Weather Service, we expect daytime highs in the triple digits for at

least the next week. We also want to remind people that the water temperatures remain very

cold, and we urge caution for those who may be participating in water recreation.

During hot periods, it is a good idea to check water stores, supplies of important medications

and air conditioning systems in homes and businesses. If you know of neighbors or friends

who might benefit from assistance during the coming hot weather, this might be a good time to

check on them.


It is important to wear appropriate clothing during hot weather, such as light-weight, light-

colored clothing, especially for children. Wearing a hat and using sunscreen is a good idea if


you plan to be outside. If you are unaccustomed to working or exercising in hot weather, it is

important to pace yourself, drink 16 to 32 ounces of liquids every hour if you must be active

in the heat, and include some foods, juices or sports drinks to replace electrolytes (salts in the

blood). It is a good idea to look at the weather forecasts in your planning, and consider

avoiding rigorous activity in the hottest parts of the day.

If you or someone you are with develops dizziness, headache, flushed skin or nausea,

consider heat illness (heat exhaustion). Heat stroke occurs when a person exposed to extreme

heat loses the ability to maintain a normal body temperature, and can lead to confusion,

unconsciousness, or even death. Please consult with your primary care physician or health

care provider if you find yourself or another person experiencing these physical symptoms.

For relief from hot weather, public buildings like the Tuolumne County Library are

available according to their usual business hours. The Main Library will be open from

10:00 AM to 6:00 PM, Tuesday through Saturday. Other library hours can be obtained by

calling 209-533-5507. The Tuolumne County Senior Center, also on Greenley Road, is

open from Monday through Friday, 8:00 AM to 4:00 PM, except on holidays, hours can be

obtained by calling 209-533-2622.  (G. Carroll)
