Area Forecast Discussion National Weather Service Jacksonville FL 919 PM EDT Mon Sep 21 2020

. AREAS OF COASTAL FLOODING AND BEACH EROSION ALONG THE NE FL/SE GA ATLANTIC COASTAL AREAS AND ST JOHNS RIVER BASIN .

UPDATE.

Northeast to east low level flow continues to bring in moist air for the northeast FL area with areas of low clouds and isolated to scattered showers. Locally enhanced moisture coming into eastern parts of northeast FL may result in scattered moderate showers to the northeast FL coastal zones south of Mayport tonight, but should gradually weaken as the push into the inland zones toward Clay, Putnam, Alachua and Bradford counties. Showers will be shallow in depth, with a strong subsidence inversion noted on our 00Z JAX sounding at 6800 ft, and these showers will move quickly west- southwest Otherwise. breezy northeast winds continue for coastal areas, with strongest winds right at the coast with gusts near 40 mph possible for part of tonight. Lows tonight will be in the upper 50s/lower 60s southeast GA, and 60-65 inland northeast FL and 65 to 70 close to the northeast FL coast.

MARINE.

Coastal marine forecast was on track with Gale warning remaining in effect due frequent gusts of gale force. Winds expected to gradually come down tonight with Small Craft Advisory then going into effect. Seas from guidance appeared on track with 9-10 ft nearshore buoys.

Coastal Flood: Minor tidal flooding along the St Johns River Basin and along the Atlantic coastline will continue through Tuesday with levels about 1 to 2 feet above astronomical high tide. Flooding on some streets and parking lots to be expected along the coast. Due to the onshore flow and St Johns River character, we may be looking at a week or more before any normal astronomical tides would develop.

PREV DISCUSSION [732 PM EDT].

NEAR TERM [Through Tonight].

Strong, deep layer ridge of high pressure in place over the region with the low level portion of the ridge centered over the Appalachian mountains. This has led to breezy northeasterly winds today gusting to near 40 mph, mostly along our coastline. This has also led to a host of other coastal hazards including a high risk of rip currents, high surf, and coastal flooding. The strongest winds and worst coastal flooding should subside this evening, but won't go completely go calm overnight.

Onshore flow has also allowed the development of isolated to scattered showers, again mostly along the coastline. Rounds of light to moderate showers will continue into tonight, but should dissipate across the area by midnight.

SHORT TERM [Tuesday Through Wednesday Night].

Low level ridge of high pressure will slide south through mid-week and weaken, allowing low level winds to become lighter and more easterly. With continued onshore flow and seasonally high tides, minor coastal flooding, high rip current risk, and elevated surf heights will continue through Wednesday morning. A cool, dry air mass in place with highs in the upper 70s to low 80s and lows in the upper 50s to upper 60s. Isolated showers possible on Tuesday, but airmass will likely be too dry for shower development Wednesday.

LONG TERM [Thursday Through Monday].

Ridge of high pressure will begin to shift eastward offshore at the end of the work week, with southeasterly flow returning moisture to the area ahead of a developing cold front starting Thursday. Isolated to scattered storms will return around Thursday-Friday as a result of this return flow of moisture. Front may not reach our area until early next week, but scattered storms appear likely through the weekend out ahead of it. Temperatures will trend above normal, with highs mostly in the 80s and lows in the upper 60s to low 70s.

AVIATION. [Through 00Z Wednesday]

Continuation of low clouds expected tonight with clouds moving in off the warm Atlantic waters. Though not much widespread MVFR at this time, forecasting periods of MVFR CIGs later tonight again for northeast FL, and we still have a chance of an isolated shower for northeast FL coastal TAFs for most of the night. Winds will remain elevated and gusty but will tend to diminish tonight. Winds to remain more elevated through the night along the coast and into Tuesday. Inland winds will become gusty again Tuesday morning.

MARINE.

The strong low level ridge of high pressure to our north will gradually sink south and weaken over the next few days. Northeast winds at 20 to 25 knots with frequent gusts to gale force this evening will subside to 15 to 20 knots by early Tuesday morning. Waves will take longer to lower, with seas of 7 feet or higher possibly lasting past Wednesday morning, particularly over our offshore waters. Mostly dry conditions should continue through Thursday. As we head into the weekend, our next front will approach the area, bringing an increase in chances for showers and thunderstorms.

Rip Currents: High risk of rip currents in effect for NE FL and SE GA beaches through Wednesday morning. High surf advisory in effect along NE FL beaches through Wednesday morning, along SE GA beaches through Tuesday morning.

Coastal Flood: Worst of the coastal flooding should subside with this afternoon's high tide cycle, but water levels along the Atlantic coastline and the St. John's River for the next several days. Coastal flood warning remains in effect through 6 PM ET and then a coastal flood advisory will take its place.
