Synopsis for Atlantic coastal waters from Flagler Beach to Jupiter Inlet out 60 nm - AMZ500
1021 AM EST Wed Jan 22 2020

A low pressure developing north of the Bahamas today will continue to bring north winds with frequent gusts in excess of gale force through this evening. The pressure gradient will start to relax tonight through Friday as the low pulls away from the area, but hazardous seas will remain across the waters. Another cold front is forecast to cross the waters Friday night into Saturday morning veering winds back to northwesterly and continuing poor to hazardous conditions into the weekend.

Gulf Stream Hazards: North winds 30 to 35 knots with frequent gusts as high as 40 to 45 knots through this afternoon. Seas building to 15 to 18 feet. Seas will likely remain above advisory criteria through Saturday.

Secondary circulation/low west of low pressure farther offshore has shown up well on satellite imagery this morning, currently shifting south toward Grand Bahama this morning. The closer proximity of this system has significantly tightened the pressure gradient, and Buoy 41009 20 nautical miles offshore of the Cape has been recording sustained winds up to 40mph (35kts) with gusts to 50 to 55mph (45-48kts). At the Cape and along the Volusia County coast, occasional 40 to 45 mph gusts have been reported. It will remain quite windy today, especially along the coast, with a Wind Advisory in place through early this evening as northwest to north winds around 20-25 mph continue to gust as high as 35 to 40 mph. A Lake Wind Advisory is in effect across the interior for winds 15-20 mph, gusting to 25 to 30 mph.

These strong winds were able to transport in a chilly airmass for central Florida standards, with lows just below freezing (lowest around 30 degrees) occurring across Lake, inland Volusia and portions of northwest Orange and western Seminole counties. Wind chill values in the 20s and low 30s were experience over much of the area from these colder temperatures and gusty winds. As low off the coast shifts farther south and weakens, winds aloft will continue to veer the northeast, quickly modifying the colder airmass and transporting increasing cloud cover and showers onshore. Temperatures will still be below normal with highs in the upper 50s northwest of I-4 and low to mid 60s farther south and inland.

Strong northerly winds and increasing wave heigheights will lead to very dangerous surf conditions at area beaches, with a High Surf Advisory and High Rip Current Risk in place.

Marine
Gale conditions will continue over the waters today, with seas building to 15 to 19 feet over the gulf stream. The Gale Warning continues through 7 pm. For the nearshore, a Small Craft Advisory will go into effect after 4 pm and expand offshore after 7pm. And even though winds are forecast to drop below 20 knots late tonight, seas will still range 7 to 12 feet.
