Heat Wave: Excessive heat warning in effect Sunday as risky conditions persist


Mayor Lovely Warren has initiated a Cool Sweep Heat Emergency operation in anticipation of forecasted temperatures exceeding 90 degrees.

"The combination of hot temperatures and high humidity will combine to create a risky situation in which heat illnesses are likely", the National Weather Service said.

Excessive Heat Watch means the heat index will reach 100-105 degrees.

For Monday, July 2, that record of 102 degrees may also be tested. Today will be a noticeably hotter day as highs climb into the mid to upper 90s by the afternoon, and while humidity levels will inch up compared to today, it will still only be moderately humid. By this afternoon, dew points inch up into the low 60s which makes the humidity a bit more of a factor.

Scattered storms will be likely Saturday night although most models have backed off on rainfall amounts (still one that indicates some healthy rainfall totals) but something to keep an eye on. The records for both Friday and Saturday were 100° and Sunday's is 99°.

Heat index values as high as 96 to 102 degrees are expected on Monday.

The heat will stick around during the first week of July. "Drink plenty of water, use air conditioning or go to an air-conditioned place, and avoid strenuous outdoor activity during the periods of intense heat". Some residents are urged to limit their time outdoors including young children, the elderly and those with respiratory problems. The National Weather Service in Mount Holly predicts the heat will hang over the state through at least Tuesday and may continue through Wednesday. On Saturday the peak heat index values were hotter than they were Friday in the upper 100s.

It is very easy to get dehydrated when it is so hot and humid. In Pontiac, it felt closer to 115 degrees, according to the National Weather Service.

"This weekend is going to be quite hot". Temperatures are expected to drop to to a low around 70 degrees overnight into Monday, the weather service said.
