It will be breezy and very warm Monday with forecast high temperatures climbing into the upper 80s. It will feel close to the mid-90s when you factor in the humidity.

The wind will also be increasing out of the east due to an upper level low over the Bahamas and a ridge of high pressure over the Deep South and Gulf creating a tight pressure gradient.

The strong onshore breeze is leading to a dangerous high risk of rip currents along our Atlantic beaches. It's not safe to go swimming in the ocean. Small craft should exercise caution over the Atlantic waters and Keys waters due to choppy conditions on the bays and nearshore.

We will remain unsettled Tuesday with the potential for passing storms, especially in the morning through midday. As the east breeze persists, most of the storms will push inland by the afternoon.
