WILMINGTON, N.C. (WECT) - Wilmington’s highest hourly heat index ob was 113 Monday, and you’ll need to brace for similar stressful to dangerous metrics Tuesday.

Humidity will stay crazy high all week and, with it, popup storm chances: 20% Tuesday, 50% Wednesday, 30% Thursday, and 50 to 60% Friday, Saturday, and Sunday.

Good news! New tropical storm formation remains unlikely in the Atlantic Basin this week. Last week’s disturbances have missed their development windows.
