I personally, love it hot! But with that beautiful heat, comes some dangers so awareness and planning are key!
Watches, Warnings and Advisories for Extreme Heat
Excessive Heat Outlooks: Are issued when the potential exists for an excessive heat event in the next 3-7 days. An Outlook provides information to those who need considerable lead time to prepare for the event, such as public utility staff, emergency managers, and public health officials.
Excessive Heat Watches: Are issued when conditions are favorable for an excessive heat event in the next 24 to 72 hours. A Watch is used when the risk of a heatwave has increased but its occurrence and timing are still uncertain. A Watch provides enough lead time so that those who need to prepare can do so, such as city officials who have excessive heat event mitigation plans.
Excessive Heat Warning/Advisories: Are issued when an excessive heat event is expected in the next 36 hours. These products are issued when an excessive heat event is occurring, is imminent, or has a very high probability of occurring. The warning is used for conditions posing a threat to life. An advisory is for less serious conditions that cause significant discomfort or inconvenience and, if caution is not taken, could lead to a threat to life.
NOAA’s heat alert procedures are based mainly on Heat Index Values. The Heat Index, sometimes referred to as the apparent temperature is given in degrees Fahrenheit. The Heat Index is a measure of how hot it really feels when relative humidity is factored in with the actual air temperature.
To find the Heat Index temperature, look at the Heat Index chart below. As an example, if the air temperature is 96°F and the relative humidity is 65%, the heat index–how hot it feels–is 121°F. The National Weather Service will initiate alert procedures when the Heat Index is expected to exceed 105°-110°F (depending on local climate) for at least 2 consecutive days.
Tips for Preventing Heat-Related Illness
Drink more fluids (non-alcoholic), regardless of your activity level. Don’t wait until you’re thirsty to drink. Warning: If your doctor generally limits the amount of fluid you drink or has you on water pills, ask how much you should drink while the weather is hot.
Don’t drink liquids that contain alcohol or large amounts of sugar–these cause you to lose more body fluid. Also, avoid very cold drinks, because they can cause stomach cramps.
Stay indoors and, if possible, stay in an air-conditioned place. If your home does not have air conditioning, go to the shopping mall or public library–even a few hours spent in air conditioning can help your body stay cooler when you go back into the heat. Call your local health department or Red Cross chapter to see if there are any heat-relief shelters in your area.
Electric fans may provide comfort, but when the temperature is in the high 90s, fans will not prevent heat-related illness. Taking a cool shower or bath, or moving to an air-conditioned place is a much better way to cool off.
Although anyone can suffer from heat-related illness, some people are at greater risk than others. Check regularly on:
Infants and young children
People aged 65 or older
People who have a mental illness
Those who are physically ill, especially with heart disease or high blood pressure
Visit at-risk adults at least twice a day and watch them for signs of heat exhaustion or heat stroke. Infants and young children, of course, need much more frequent attention.
If you must be out in the heat:
Limit your outdoor activity to morning and evening hours
Cut down on exercise. If you must exercise, drink two to four glasses of cool, nonalcoholic fluids each hour. A sports beverage can replace the salt and minerals you lose in sweat. Warning: If you are on a low-salt diet, talk with your doctor before drinking a sports beverage. Remember the warning in the first “tip” (above).
Try to rest often, in shady areas
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).
I really hope we have a sunny hot summer! Remember to be aware and be safe Minneapolis!
