Area Forecast Discussion National Weather Service Melbourne FL 431 AM EDT Sun Sep 20 2020

DISCUSSION. Today-tonight . Expecting the wind, wave, and coastal flood portions of our multi-hazard event to be realized today, with a smorgasbord of advisories and warnings in effect.

The northeasterly wind surge due to a tight pressure gradient between a strong high pressure over the eastern seaboard and the small low pressure system off of the east coast of FL, will push southward through the day, reaching the southern Treasure Coast by this evening. Both the HRRR and the GFS indicate 925mb winds of 34+ kts pushing into northern parts of the area this morning, then reaching the Treasure Coast this afternoon. Thus, have issued Wind Advisories from Osceola/Indian River Counties northward, with Lake Wind Advisories beginning for the Treasure Coast Counties at noon. Gusty to windy conditions today, with gusts reaching up to 40 mph, especially along the Volusia and Brevard barrier islands.

High rain chances will continue today, as strong northeast winds push moist air, with forecast PWATs around 2.5", onshore. Highest chances will be this afternoon, with peak PoPs 60-70% area-wide. Showers will initially continue moving ashore from the Space Coast northward, before spreading south through the day. Lower chances of thunder again today, with just isolated storms expected. With ample moisture, there will be a localized flooding rain threat, especially at the coast, where WPC has designated a "Marginal" risk of excessive rainfall. While storm motions are expected to keep storms from persisting over one area for a prolonged period of time, this threat will be heightened in areas that have recently received rainfall or see several rounds of showers and a few storms. Clouds, showers, and windy NE flow will keep high temperatures slightly below normal in the mid 80s, except for the Treasure Coast, which looks to remain near normal in the upper 80s.

Winds look to remain elevated overnight, especially along the coast, but are expected to drop to around 10-15mph across the interior after midnight. Rain chances will shift primarily offshore for the overnight, but at least a chance of showers looks to linger past sunset, especially for coastal counties. Despite cooler highs, lows look to remain in the mid 70s, with upper 70s along the coast due to the strong onshore flow.

At the coast, a Coastal Flood Warning is in effect from southern Brevard County northward, with a Coastal Flood Advisory for the Treasure Coast. Significant coastal flooding and beach erosion is expected over the next few days. Impacts will be greatest during the times of high tide, which will be from 1000 and 1100 AM.

Coastal residents should be alert for protecting beachfront property. In addition, large breaking waves of 6 to 11 feet are expected in the surf zone, with a high to extreme risk of rip currents. Entering the water is not advised. For complete information on all of the products currently in effect, see each product listed on the home page of our website.

Mon . High pressure will nose southward from the mid-Atlc region early this week. Expect another breezy day to develop with mild onshore flow. Some dry air is forecast to makes its way into our area by Monday, lessening rain chances to 20-40 percent. Variable clouds and a marine influence will keep afternoon highs in the low/mid 80s. Night time with lows in the low/mid 70s.

Tue-Sat . The ridge north of the area will expand across the SE states by midweek, weakening the pressure gradient and lessening winds across the area on Tuesday through midweek. Airmass drying will diminish rain chances to just 20 percent for showers through Wed. Onshore winds will keep a strong marine influence, keeping temperature ranges in check with highs averaging in the low/mid 80s and lows in the upper 60s to low 70s. Return flow around periphery of departing ridge combined with unsettled conditions upstream look to increase rain chcs a little more to the sct category into the latter portions of the week.

AVIATION. Gusty to windy conditions expected today, especially across northern coastal terminals. NE wind gusts 25-30kts this afternoon from KMLB northward, before gusts approaching 25kts shift southward to the Treasure Coast terminals later this afternoon into this evening. MVFR conditions largely prevailing today, as showers push onshore. High rain chances across the area today, with VCSH included through the afternoon at all TAF sites. TEMPOs for SHRA will likely be needed as the day continues.

MARINE. Today-tonight . Dangerous boating conditions, with Gale Warnings in effect for all Atlantic zones, due to strong NE winds from a tight pressure gradient. Winds 20-30kts spreading southward towards Jupiter Inlet through the day, with seas rapidly building to at least 15ft by this evening. High coverage of showers pushing onshore today through the overnight, with an isolated thunderstorm possible.

Beach erosion will remain present at area beaches into early Tuesdays high tide. See below for times of high tide at selected beaches.

Monday-Wednesday . Seas forecast to remain dangerous, well into double digits offshore on Monday. Hazardous conditions continue over all the waters through at least midweek due to the combination of various swell sources and local winds. Seas may diminish to caution criteria perhaps near shore by around Thursday.

HYDROLOGY. The Saint Johns River at Astor remains well within Minor Flood stage. While levels are slowly increasing early this week, additional rainfall over the river basin and high tides downstream are also impeding water flow. Refer to Flood Statements from NWS Melbourne for the river levels and forecasts near Astor, which will be updated daily while the river remains in flood stage.
