Updated national weather service miami fl 1041 am edt Mon sep 25 2017 Update South florida is in a drier pocket of air this morning, which has helped to minimize convection. Hurricane maria continues well to our northwest with minimal influence over the weather. Main concern continues to be the marine hazards along the atlantic coast and waters. No additional updates expected through noon. Have a great Monday morning! Prev discussion issued 802 am edt Mon sep 25 2017 aviation... slightly drier day, though some showers and storms could develop this afternoon. Expect focus of convection to stay inland of the east coast TAF sites, though some sites could see sub-vfr conditions if directly impacted by convection. Sea breezes are expected to develop and convection will focus along boundaries and their collisions. Prev discussion... Issued 412 am edt Mon sep 25 2017 discussion... today through Wednesday: the florida peninsula will be in between hurricane maria, as it continues its northward track well to our east, and a broad upper level low over the northern gulf coast. This low is expected to briefly merge into the larger circulation around maria early this week, leaving a trailing upper level trough across the state. West to occasionally northwest flow around these features will bring drier air into much of the state, leaving a moisture gradient across south florida. Both seabreezes will develop the next few afternoons, though the wind direction will mean a late start to the east coast seabreeze as it remains relatively near the coast. Expect showers and a few storms to develop along the seabreezes during the afternoons, favoring the east coast late in the day. Overall rain chances will remain below normal the next few days. If the dry air is able to penetrate far enough south, wouldn't be surprised if areas near the lake remain completely dry on some days. Late week: hurricane maria is forecast to brush the outer banks mid week before racing off to the northeast across the open atlantic. As it does, the upper level low that briefly merged with the larger circulation around the storm will be left behind across the northeastern gulf north florida late week. Midlevel flow, while fairly light, will tap into deeper moisture, bringing pwats back over 2" across the region late week. Both the GFS and ECMWF are |
showing the potential for weak surface low development off to our northeast along the moisture boundary as the upper level low lifts out this weekend. Regardless, a shift back to a wetter pattern is expected across south florida to end the week. Showers and storms increase in coverage across the region by Thursday, driven by the inland movement of both the gulf and atlantic seabreezes. Depending on exactly how and where the boundary sets up, more numerous activity is expected Friday into next weekend with the potential for some heavy rainfall. Marine... Northeast swells from hurricane maria are already making their ways through the local atlantic waters, expected to peak around 5-6ft later today. This will continue to lead to seas of 7- 8ft off the palm beach county coast, with lower amounts in the remainder of the local atlantic. Both swells and seas are expected to linger through much of the week. A small craft advisory remains in effect through through late Wednesday, and may need to be extended beyond that in the coming days. The rest of the atlantic waters will reach cautionary criteria through much of the week. Winds are expected to be light and seabreeze driven through the week, with no boating concerns in the gulf waters. Beach forecast... Long period northeasterly swell potentially reaching 5-6ft the next few days at periods of 12-13 sec will create the potential of 10+ foot breakers along the palm beach county coast. A high surf advisory remains in effect for coastal palm beach county highlighting the threat of coastal erosion and dangerous surf conditions through much of the week. In addition a high risk for rip currents will be in place at all atlantic beaches through much of the week.
