Summer’s heat is returning with a vengeance.
Heat Advisory
A heat advisory has been issued for all of Metro Detroit and much of Southeast Michigan, including Genesee, Livingston, Oakland, Macomb, Washtenaw, Wayne, Lenawee, and Monroe counties for Tuesday from 10 a.m. to 10 p.m. The advisory is for heat indices as high as 102 degrees.
The National Weather Service issues a heat advisory in Southeast Michigan when the heat index is forecast to be 100 degrees or more for at least three consecutive hours. The advisory can continue into the night if low temperatures are expected to only fall to the 70s or higher, according to the agency.
An excessive heat warning is issued when the heat index is expected to reach and exceed 105 degrees for at least three hours. The warning is issued within 24 hours of the expected heat. An excessive heat watch precedes it.
A 4Warn Weather Alert has also been declared for Tuesday due to the heat and the chance of strong to severe storms.
During abnormally hot weather, it is particularly important to stay hydrated.
Never leave children or pets in a vehicle alone. Cars can get hotter than the outside temperature even when the windows are open.
Limit or avoid heavy exercise and other strenuous activity during the peak heat.
Find shade and air conditioning when possible.
Wear lightweight and light-colored clothing. Finally, do not forget to check on children and seniors.
While the air temperature is forecast to reach the lower 90s on Tuesday afternoon, high humidity will contribute to it feeling like the upper 90s to lower 100s for several hours.
Tuesday’s record high is 98 degrees, which was set on Aug. 27, 1948.
The hottest part of the year is already behind us. July is normally the hottest month of the year. Metro Detroit’s average high is 80 degrees for most of this week. By the end of the week, Aug. 30, the average high falls to 79 degrees.
