Area Forecast Discussion National Weather Service Jacksonville FL 736pm EDT Tuesday Oct 8 2024 Near Term Issued at 340pm EDT Tuesday Oct 8 2024 Shower activity remains limited this afternoon as a drier airmass from the north clashes with tropical moisture south of a stalled front well ahead of Hurricane Milton. Satellite estimates of PWATs well under one inch are noted northwest of a line from about Nassau County southwestward across Gilchrist County as the front has made it about as far south as the I-10 corridor. Showers will continue into the night tonight for southeastern areas as the approach of Hurricane Milton from the southwest pushes tropical moisture further north. The front will therefore lift northward across the area into the morning hours as outer rain bands from Milton work their way into the rest of the area from south to north towards sunrise. However, more significant impacts are not anticipated during the near term period. Breezy onshore conditions will continue through this evening and into overnight hours however, with winds in the 10-20mph range with gusts to near 25-30mph. Towards sunrise, expecting these conditions to start to pick up, especially by the coast and over the St. Johns River Basin. Slightly more mild tonight with temperatures in the mid to upper 60s north and west and low to mid 70s south and east. .SHORT TERM... (Wednesday through Thursday night) Issued at 340pm EDT Tuesday Oct 8 2024 Hurricane Milton will continue on its trek towards the west coast of Florida through Wednesday, making landfall during the overnight hours into Thursday. Milton will move across the Florida peninsula through Thursday and begin to exit off towards the Atlantic by the overnight hours from Thursday into Friday. For local impacts, the outer rain bands from Milton will begin to trickle into the area through the day on Wednesday, with Tropical Storm forced gusts expected to arrive by Wednesday morning, with Tropical Storm force sustained winds expected for most of NE FL and along the SE GA coast, with frequent hurricane force gusts highly possible for our north central Florida counties and along the St. Johns River basin. In addition to the wind threat, the threat of flash flooding is possible as Milton is expected to bring 5-12 inches of rain, with locations in north central Florida (Marion, Putnam, Flagler) as well as St. Johns county likely to see the greatest total of rainfall for NE FL and SE GA. Coastal locations as well as along the St. Johns River can expect to see storm surge of 3 to 5 feet and 2 to 4 feet respectively. Milton will begin to move offshore to the Atlantic during the overnight hours on Thursday night, gusty conditions and showers along coastal locations will be possible through the night. Long Term (Friday through next Tuesday) Issued at 340pm EDT Tuesday Oct 8 2024 High pressure will build into the area after Milton's exit off towards the Atlantic. Some lingering showers along coastal locations in NE FL, from Duval south towards Flagler, will be possible during the morning hours, with chances diminishing through the day on Friday. By the weekend high pressure stationed over the area will allow for a dry weather pattern to settle into the area. A dry cold front will begin to move into the area by the upcoming work week, keeping Probability of Precipitation near nil. Marine Issued at 340pm EDT Tuesday Oct 8 2024 A Hurricane Warning for the Florida waters and a Tropical Storm Watch for the Georgia waters currently in effect as Hurricane Milton is expected to move east across the Florida peninsula late Wednesday night. Increasing rain chances with numerous to widespread rainbands are expected to occur by Wednesday morning and continue into Thursday morning. Tropical storm force winds could begin as early as Wednesday afternoon with hurricane force winds possible Wednesday night. Strong winds will still continue in the northwest quadrant of Milton into Thursday night as to pulls away from the east coast. Strong north winds and very rough seas are expected to continue on Friday. Rip Currents High Risk of Rip Currents through the rest of the week as Hurricane Milton nears the area. Hydrology Issued at 340pm EDT Tuesday Oct 8 2024 Storm Surge Warning is in effect for the northeast Florida coast and St Johns river, with SE GA coastal locations remaining in a Storm Surge Watch, for increasing confidence in life threatening storm surge as Milton makes landfall Wednesday evening near the west central Florida coast. Storm surge inundation is possible as Milton moves from the west central Florida coast across the Florida peninsula with inundation amounts up to 3 to 5 ft along the coast and up to 2-4 ft in the St Johns River. Rivers: SE GA: Major river flooding is ongoing along the Alapaha River in Statenville and will continue through Wednesday night. The Altamaha river at Charlotteville, Baxley and Doctortown was falling from crests in Minor flood stage with the lower Altamaha River in Minor flood stage at Everett City nearing a crest just below Moderate Flood stage mid-week. The Satilla is expected to rise into Minor stage later today. NE FL: There is an increasing risk of river flooding at NE FL rivers due to Milton's rainfall footprint mid-week, include Black Creek and the upper Santa Fe. As flood waters travel down the Suwannee River, backwater flooding up the lower Santa Fe including at Three Rivers Estates will rise from Minor flood stage toward Moderate flood stage late this week. The Southeast River Forecast Center started to include 72 hour rainfall forecasts into the river models (typically only 48 hrs of rainfall) to assist with Milton preparations. Local river interests, please continue to routinely monitor river forecasts over the coming days, especially for our quickly responding rivers including the Black Creek basin.
