| Area Forecast Discussion National Weather Service Tallahassee FL 219am EDT Tuesday July 21 2026 ...New SHORT TERM, LONG TERM, Marine IRE WEATHER,Hydrology .KEY MESSAGES... Issued at 218am EDT Tuesday July 21 2026 - Tropical Storm Bertha continues to bring squally weather from the coastal to inland counties via outer rainbands through Wednesday. Gusty winds and brief periods of torrential rain are the main concerns. - Tropical Storm Watches remain in effect for southern Walton and coastal Bay counties where tropical storm conditions are possible within stronger rainbands. - Dangerous beach and marine conditions are expected much of the work week. A High Risk of rip currents is forecast the next several day at all area beaches along with High Surf. It is strongly discouraged to enter the surf on high risk days. Please heed the beach flags and advice from local officials. .SHORT TERM AND Long Term (Today through Monday) Issued at 218am EDT Tuesday July 21 2026 Tropical Storm Bertha will continue to send periodic bands of rain through our area through Wednesday. Very heavy rain and gusty winds can be expected as these outer rain bands move ashore and inland the next couple of days. Ponding on the roadways and isolated instances of flash flooding are the primary concerns within any of the rain bands as they'll be incredibly efficient rain producers that could drop a quick inch or two in 15-30 minutes. Temperatures today are forecast to remain in the middle 80s to near 90 thanks to the passing showers from Bertha's outer rain bands. They'll moderate back into the upper 80s to lower 90s Wednesday as the rain bands decrease in coverage as Bertha trudges west. The tropical airmass around Bertha will migrate westward along with it for Thursday. This leads to isolated to scattered showers and thunderstorms Thursday afternoon, or very summer-like. An H5 trough diving into the Northeast and Mid-Atlantic states Friday and Saturday will send a front into the Southeast. This front is forecast to stall nearby and will lead to elevated rain chances over the weekend. Where it ultimately stalls remains in question at this time, which is important because locally heavy rain will be possible along the stalled front. As of now, most deterministic, ensemble, and AI guidance has it stalling north of our area, but we'll continue to monitor things as we get closer. Daytime highs will rebound back into the lower to middle 90s Thursday and beyond with overnight lows in the middle 70s. Heat indices will generally run between 100 to 105 later this week into the weekend. Marine Issued at 218am EDT Tuesday July 21 2026 At 10pm CDT Monday, the center of Tropical Storm Bertha was located 140 miles south of Panama City. Bertha has been meandering and is nearly stationary. A slow west-northwestward or westward motion is expected to begin on Tuesday. Maximum sustained winds were near 35 knots, or 40 mph. Some additional strengthening is possible on Tuesday. Over the northeast Gulf waters, winds will continue to strengthen through Tuesday before slowly diminishing east to west Wednesday into Wednesday night as Bertha moves away. Several bands of tropical downpours capable of producing gusty winds and waterspouts are forecast through at least Wednesday. Fire Weather Issued at 218am EDT Tuesday July 21 2026 Fire weather concerns will remain low through Wednesday thanks to occasional tropical downpours from Tropical Storm Bertha's outer rain bands. However, these rain bands will contain some gusty winds in excess of 20 mph. Gusty winds are forecast outside of any rain, especially along the immediate coast. Hydrology Issued at 218am EDT Tuesday July 21 2026 Rainbands from Tropical Storm Bertha continue to move inland across much of the region. Widespread rainfall amounts of 0.5-1.5 inches are expected through the next couple of days, with heavier amounts possible near the immediate coast. The flash flood risk is greatest south of I-10 where several bands may train over the same location. There are no concerns for river flooding given these rainfall amounts. Persistent onshore flow in Apalachee Bay will lead to minor coastal flooding on the next high tide Tuesday morning. Water levels of 2 to 2.5 ft MHHW are expected along the immediate coast. This typically results in flooding of low-lying beach access roads and other coastal adjacent properties. In the Florida Panhandle west of Indian Pass, water levels are running above normal by about 1.5 ft even with offshore flow. As wind directions shift to be more onshore later tonight and into Tuesday, a period of coastal flooding around the high tides late tonight and late Tuesday night is expected. Water levels of 1.5 to 2 ft MHHW are expected along the immediate coast. This typically results in flooding through beach access areas into parking lots and some low-lying roads along the immediate coast. As Tropical Storm Bertha moves further away from the area on Wednesday, water levels along the coast should drop enough where advisories are no longer necessary.
