A gentle to moderate breeze will persist with brief increases in winds with any thunderstorm development. Conditions for small craft operators will remain poor this afternoon, as swells from distant Hurricane Epsilon slowly subside.

Morning soundings show the significant difference in PW values across the state, with JAX at 1.7" and MFL at 2.4" where deep tropical moisture has lifted northward into the southern FL peninsula from an inverted trough stretching northeast from TS Zeta. With central Florida in the middle of drier conditions to the north and deeper moisture to the south, rain chances will follow suit, with higher rain chances across areas south of a line from Orlando to the Cape, increasing up to 60-70 percent. Highest PoPs and greatest potential for locally heavy rainfall will be across these south central FL areas, especially the Treasure Coast.

Sufficient low level steering will exist to keep showers moving north to northeast today, but weaker winds at 700mb will lead to slower storm motion this afternoon. Repeated rounds of showers or any storms will be capable of producing rainfall totals today into this evening up to around 1-2 inches with localized higher amounts to 3-4 inches possible across St. Lucie and Martin counties. Highs will reach the low to mid 80s south of Orlando, where greater cloud cover and higher rain chances exists. Toward and north of the I-4 corridor, highs will be in the upper 80s, where lower PoPs, around 20-30 percent, and less cloud cover is expected.

Even with swells from distant Hurricane Epsilon continuing to subside, they will still produce a High Risk for Rip Currents at area beaches today. Rough surf will also continue and entering the water is not advised.

Marine
Swells will continue to subside today, with seas falling to 4-6 feet. Will allow SCA (Small Craft Advisory) to expire offshore, but will maintain exercise caution headlines for much of the adjacent Atlantic. Winds will generally be out of the south through late morning up to 10-15 knots south of the Cape, then becoming east to southeast in the afternoon. Any storm activity will increase winds and seas locally.

Hydrology
The latest forecast has the Saint Johns River at Astor continuing a slow decrease within Minor Flood Stage through the upcoming week. Elsewhere, the Saint Johns River at Sanford and near Lake Harney is forecast to stay within Action Stage, while at DeLand the river is forecast to continue below Action Stage. Refer to daily Flood Statements and River Statements from NWS Melbourne for the latest river levels and forecasts.
