Posted at 6:10 AM, Aug 31, 2023

WEST PALM BEACH, Fla. — Lingering tropical moisture from the "trailing tail" of post-tropical storm Hurricane Idalia will continue to have healthy rain chances through the end of the week.

We'll see a break in the action overnight with storms developing through the day on Friday.

A weak frontal boundary sliding south on Friday will interact with moisture from Idalia, resulting in higher rain chances during the afternoon and early evening.

Temperatures on Friday will be in the low 90s with a heat index in the low triple digits

We'll then see lower dewpoints and lower rain chances starting on Saturday and lasting through the next several days.

Idalia is weakening and all warnings have been discontinued for the east coast.

On this track, Idalia will move away from the Carolina coast tonight and toward Bermuda over the weekend — where a tropical storm watch is now in place.

Idalia is forecast to become a post-tropical cyclone tonight but is expected to strengthen back to a tropical storm this weekend.

Hurricane Franklin is moving away from Bermuda and is not impacting any other land areas.

Tropical Storm Jose is moving northward and will be quickly absorbed by the circulation around Franklin.

There are two other additional waves in the Atlantic — one in the central Atlantic near Jose and the other one in the far eastern tropical Atlantic. We'll continue to monitor them, but they do not pose threats at this time.
