JACKSONVILLE, Fla. – Dangerous heat is back today across Northeast Florida and Southeast Georgia, and a Heat Advisory will be in effect from 11 a.m. to 7 p.m.
Along the coast, heat index values could reach 110 degrees during the early to mid-afternoon hours. Inland, along the U.S. Highway 301 corridor, values are expected to peak around 108 degrees. Even areas not in the advisory are expected to feel like 100-107 degrees through the afternoon.
Today, winds are blowing from the west, which will delay the east coast sea breeze until early afternoon.
Evening forecast
Scattered to numerous storms are expected to develop from west to east across northeast and north-central Florida during the late afternoon and early evening hours. Some of those storms could turn strong to severe.
The biggest storm threats include:
Damaging wind gusts of 40-60 mph from a weather phenomenon called a downburst — essentially a powerful blast of air that slams down from a storm and spreads out in all directions at ground level
Frequent lightning strikes
Heavy downpours in localized areas
