Tonight

5-Day Outlook

Major heat risk today across the Coastal Plains and Brush Country this afternoon as heat indices climb to 110-114°F. A Heat Advisory is in effect from noon to 7 PM this evening as high temperatures combine with high relative humidity. Please practice heat safety!

Mostly sunny along beaches today with high temperatures in the upper 80s and a very high UV index. South to southeast winds around 20 mph. There's a low risk for rip currents today but low risk does not mean no risk. Dangerous rip currents are possible especially near piers and jetties.

Mostly clear and muggy tonight with lows in the upper 70s to lower 80s. Southeasterly winds between 5-15 mph.

Low rain chances through the work week, with rain chances increasing to 40-60% on Thursday as moisture increases. Heat will remain our greatest concern with max temperatures well into the 90s and in the triple digits inland. Low temperatures provide little to no relief, from the mid 70s to lower 80s.
