East-Central Florida - Friday August 9, 2024: A little more sunshine is expected today, aggravating the already unusually high temperatures in our region. Combined with the ongoing high humidity we'll have another day of dangerous peak heat indices up to 110. As a result, for the second day in a row, the National Weather Service Office in Melbourne has issued another a Heat Advisory.
This afternoon, as usual, scattered storms will develop and move eastward providing some relief to the heat, but those storms also pose the threat of lightning strikes and gusty winds.
Forecasters say there is also a chance for an east coast sea breeze to form, but it will remain largely pinned to the coast, possibly reaching only as far as I-95 along the Treasure Coast.
Hazardous Weather Outlook for East-Central Florida
EXCESSIVE HEAT IMPACT
A Heat Advisory is in effect for all of east central Florida today. High temperatures in the low to mid 90s combined with muggy conditions will cause peak heat index values between 105-109 degrees. That is within Major Heat Risk range.
These unusually hot and, at times, dangerous temperatures will persist into the weekend, and Moderate to Major Heat Risk conditions are expected to continue.
If spending time outside, drink plenty of fluids and take frequent breaks in the shade or in an air conditioned building. Know the signs of heat stress.
