| Area Forecast Discussion National Weather Service Miami FL 624am EST Monday Dec 15 2025 .SHORT TERM... (Today through Tuesday) Issued at 320am EST Monday Dec 15 2025 Surface observations and satellite imagery show the leading edge of an Arctic air mass moving across SoFlo, triggering strong cold air advection today. Northerly winds spreading across SoFlo will gradually veer NE throughout the day as a strong 1040mb high over the E CONUS gradually migrates eastward towards the Atlantic seaboard. This will result in having the stronger winds affecting the immediate Atlantic coastline with speeds and gusts to advisory levels at times. Model ensemble data indicates that these winds are likely to be in the seasonal 10th percentile. Therefore, a wind advisory is now in effect for coastal locations along the east coast starting at 6AM EST, especially for gusts to 35 mph. Even occasional coastal gusts around 40 mph can't be ruled out, especially during the afternoon hours. The rest of the metro areas could see gusts of 25-30 mph at times. Unsecured objects like christmas decorations and potted plants could be blown away. Motorists operating high profile vehicles may find it difficult to drive in gusty conditions and should exercise extra caution. Also, please see the Beach Forecast section below for more details on the hazardous surf and rip current conditions along the Atlantic beaches today. Lingering moisture over the Atlantic waters may push into the coastline at times and bring quick passing showers, or even a brief thunderstorm through this afternoon. This moisture will combine with a solid low inversion and the cold air advection to push a low cloud deck across the area today. By Tuesday, the drier air gets hold of the region with models dropping Probability of Precipitation into single digits. A cooling trend will also accompany the arctic airmass arrival with highs today in the low-mid 70s. Tonight (Monday night into Tuesday morning) will be the coldest with morning lows in the low-mid 50s around the Lake region, and upper 50s to mid 60s elsewhere. Long Term (Tuesday night through Sunday) Issued at 320am EST Monday Dec 15 2025 Models remain in fair agreement in showing a sprawling ridge over the deep south states, which will continue to migrate eastward and veering winds across SoFlo to the east through the end of the work week. Prevailing subsidence and lack of deep moisture will result in very low Probability of Precipitation and no significant ran chances. Therefore, expect generally benign and pleasant weather to prevail through the forecast period. Highs and lows will gradually moderate back to the 80s in the afternoons, with near 70 degrees along the coasts each night. Marine Issued at 320am EST Monday Dec 15 2025 Northerly flow will continue to increase behind a frontal passage with strongest winds developing after 12Z, Sustained winds are forecast to be between 25-30 knots with occasional gusts to low-end Gale force. Small Craft Advisories are in effect for all Atlantic, Gulf, and Lake waters. The Advisories will taper off to only the Atlantic waters later tonight. Winds and seas should fall below hazardous levels by mid-week. Beaches Issued at 320am EST Monday Dec 15 2025 High risk of rip currents for all Atlantic beaches this morning and continuing through the next several days as coastal winds become breezy behind a frontal passage. There is also a High Surf Advisory for all Palm Beach and Broward county beaches as waves and swells increase. Highest waves along the shore could reach 9 feet or even higher at times. Beachgoers must exercise extreme caution and wait until conditions improve. NOAA Miami FL Office: Watches - Warnings - Advisories FL...High Surf Advisory until 1am EST Tuesday for FLZ168-172. Wind Advisory until 7pm EST this evening for FLZ168-172-173. High Rip Current Risk through Thursday evening for FLZ168-172- 173. AM...Small Craft Advisory until 7pm EST this evening for AMZ610.
