Current-Wednesday...Showers continue to move onshore this hour from the Space Coast south. Gauge and radar estimates indicate the highest totals continue to be from central Brevard County south, where around 2" with isolated amounts up to 4" have fallen.

Highest amounts have occurred in areas that have seen some training of showers through the morning and early afternoon. Some minor street and culvert flooding possible, should a heavier band of showers train over an area that has already seen higher rain totals today. But, storm motions around 10 mph will keep flooding threats low. Mesoscale models support these showers continuing through the afternoon for coastal and inland areas. Then, chances diminish this evening, but a chance of showers will remain through the overnight along the Treasure Coast. Expect seasonable overnight lows in the low 70s, except for mid 70s along the immediate Treasure Coast.

Breezy winds will diminish on Wednesday, as the high pressure located east of the Florida coast moves further eastward and the pressure gradient weakens. Winds around 10 mph veering southeasterly Wednesday afternoon will usher in deeper moisture from the tropics. PWATs (Precipitable Waters) 2-2.2" will support increased rain chances, with Probability of Precipitation increasing to 60-70% south of Orlando to 40-50% north. Cooler mid and upper levels will also support a chance of thunder in the afternoon. Clouds and precipitation will keep highs slightly below normal in the mid 80s.

Thu-Mon(modified previous)...Above average rain chances will exist with PWAT (Precipitable Water) values remaining near or above 2.00 inches through the period. Embedded impulses in the flow aloft will combine with the deeper moisture for widespread shower chances on Thu/Fri, numerous showers Sat/Sun, and scattered showers again on Mon. The storm threat will remain isolated to SCT each afternoon. Should see MCloudy skies for much of the period with highs below average in the L-M80s. May see a few U80s in spots if enough sun can peak through the clouds. Lows generally in the U60s to L70s, except M-U70s along the immediate Space/Treasure coasts and adjacent barrier islands.

We will continue to monitor the evolution of Tropical Storm Cristobal over the southwestern and central GOMEX through this weekend. No direct effects from the system are expected in east central Florida.

Marine
Current-tonight...Observations at buoy 41009 show seas remaining around 7 ft, with gradient winds near 20kts. So, have extended the SCA (Small Craft Advisory) for nearshore waters through 10pm. Guidance indicates winds and seas should improve later this evening and especially through the overnight, so future shifts will need to evaluate whether to continue with the 10pm expiration for all zones. Winds 10-15 kts and seas 3-5 ft expected by sunrise Wednesday.

Wed-Sun...Above normal rainfall chances into the weekend with deep tropical moisture in place, with improving conditions. Winds veering generally southerly around 10-15kts Wednesday, continuing each afternoon. Seas diminishing to 3-5 ft Wednesday will further subside to 2-4 ft through Sunday.
