Weather Impact Alert for extreme heat Sunday through Tuesday

WASHINGTON, D.C., USA — The WUSA9 Weather Team has issued a Weather Impact Alert for potentially dangerous heat Sunday p.m. through Tuesday.

When:
Sunday, Monday and Tuesday. Critical time: noon until 8 p.m. each day.

Impact:
Extreme heat with highs between 96 – 101 degrees. Heat indices between 99 – 107 degrees.

• Avoid outdoor activities. Stay in the shade if outside and take frequent breaks.
• Stay hydrated. Drink plenty of non-alcoholic beverages. Water is your best bet.
• Check on elderly, children and pets. Please do not walk your pets on concrete or asphalt surfaces.
• Know the signs of heat related illnesses: muscle cramps, headaches, vomiting, nausea, dizziness.

A Heat Advisory will likely be issued for one or more of these days. Heat Advisories are when the heat index temperatures, or “feels like” temperatures climb to 105° or higher.  If our heat indices approach 110 degrees then the Heat Advisory would be changed to an excessive Heat Warning.

Some relief is on the way by next Thursday. 

High temperature records should stay safe on Sunday but Monday and Tuesday we could see some records tied and maybe even broken.
