AMZ600: Synopsis for Jupiter Inlet to Ocean Reef FL out to 60 nm and for East Cape Sable to Bonita Beach FL out to 60 nm 337 AM EST Mon Jan 20 2020 A cold front moving across the region will bring increasing northwesterly to northerly flow today into tonight, allowing for building hazardous seas. A surface low pressure developing over the open Atlantic waters to the north of the Bahamas is forecast to create swell that will allow the elevated seas to remain in the Atlantic through a good part of the week. Gulf Stream Hazards: Hazardous winds and seas will build behind the cold front with elevated seas remaining through much of the week. The approximate location of the west wall of the Gulf Stream as of Jan 20, 2020 at 1200 UTC... - 5 nautical miles southeast of Fowey Rocks. - 7 nautical miles east northeast of Port Everglades. - 5 nautical miles east northeast of Lake Worth. - 10 nautical miles east southeast of Jupiter Inlet. |

Area Forecast Discussion National Weather Service Miami FL 324am EST Monday Jan 20 2020 ...Cold front moving through South Florida this morning... .Short Term (Today and Tonight)... Some showers have developed ahead of the cold front this morning, with a focus over the local waters where more ample moisture exists to support convection. In general, activity early today should remain shallow showers with spartan coverage. As the front pushes through the area this morning, a general drying trend is expected from northwest to southeast throughout the day. Gusty northwesterly to northerly winds will last overnight with temperatures falling into the lower 40s over Glades and Hendry Counties, 40s across the rest of Southwest Florida and inland Southeast Florida, and mid to upper 50s along the Atlantic coast. Due to the Atlantic moisture, cannot rule out some shallow showers over the Atlantic waters which could push near the coast but things should generally remain dry after the main front pushes through. Long Term - Tuesday through Sunday A shortwave trough will continue to swing southeastward across the SE CONUS and out over the Atlantic on Tuesday/Tuesday night, helping induce the formation of a surface low off the Carolina coast. This developing low will keep the gradient tight and breezy northerly winds in place over South Florida into Wednesday, when the surface low finally pushes off further into the Atlantic. This prolonged period in breezy northerly winds will leave more time for cooler and drier air to filter in across the area, making Tuesday night into Wednesday morning the coldest of the period with low temperatures ranging from the mid 30s west of the Lake/interior SW Florida to the upper 40s right along the East Coast. While frost is not expected to be a concern since winds should stay around 10mph or more overnight, a wind chill advisory (wind chill of 35 degrees or less and winds over 5 mph for 3+ hours) will be possible for some of the interior portions of the area. Wednesday will remain cool under northerly winds with high temperatures in the 60s. Winds become more easterly Wednesday night as the surface low to the northwest moves further away, kicking off a gradual warming and moistening trend stretching into the weekend. In the meantime, another shortwave trough swinging across Texas will help induce a surface low over the northwestern Gulf on Thursday. The shortwave trough begins to phase with the longwave trough as it rounds the base of it, helping drag the surface low to the northeast across the Southeast CONUS on Friday. This system should ultimately drag another cold front through South Florida on Saturday, but with the loss of upper level support by this time not much convection is expected. This second front cools things off again but not nearly as cold as the first front, with low temperatures only expected to dip into the upper 40s west of the Lake to the upper 50s/near 60 along the East Coast Sunday night. Marine Stiff northerly to northwesterly flow behind today's cold front will allow for hazardous conditions to develop in the Gulf and Atlantic waters. There will be some brief improvement for the Gulf but the Atlantic waters could see the hazardous conditions linger through a good portion of the week. Some initial Small Craft Advisory issuances will go out with this forecast package but mariners are advised to stay aware of the latest forecast as these advisories will likely change in time and require extensions into the late parts of the week. .Beach Forecast... An elevated risk of rip currents will remain along the Atlantic beaches on this Martin Luther King, Jr. Day with a high rip current risk remaining along the Palm Beaches again today. The Gulf beaches will see an elevated rip current risk develop behind the cold front that may linger through mid-week. Meanwhile on the Atlantic beaches, the elevated rip current risk will remain through the week with some of the Palm Beaches maintaining the risk into the weekend potentially. .Prev /issued 1238am EST Monday Jan 20 2020/ Aviation... Some bouts of sub-VFR cigs (and possibly vsbys) overnight into the morning hours as showers ahead of a cold front push across South Florida. Lingering low cigs in the morning should improve by midday. Gusty northwesterly to northerly flow by afternoon which should become a tad lighter overnight Monday into Tuesday to close out the forecast period.
