Gulf disturbance bears watching this week as flood threat spreads across Florida
No system has formed yet in the western Gulf, but forecasters give it a 40 percent chance over seven days while a stalled front soaks the Panhandle and pushes rain toward the peninsula.
A quiet Atlantic, a Gulf to watch
Hurricane season has been slow across the Atlantic Basin this fall, and as of Sunday evening no tropical systems were being tracked anywhere in the basin. But forecasters are watching the western Gulf of Mexico, where a low-pressure system could try to organize later this week.
The National Hurricane Center, as of Sunday evening, gave the area a 0 percent chance of development over the next 48 hours and a 40 percent chance over the next seven days, according to WUFT News. Those numbers are likely to climb as the week goes on, especially the short-range figure, WUFT reported.
No system currently exists in the Gulf, which means the weather models now in play are projecting something that hasn’t formed. Without a defined center of circulation, those models disagree on both strength and track, and any system that does develop is expected to stay over the Gulf through much of the workweek rather than moving quickly onshore. Strong north-northwest wind shear is pushing convection south of the disturbance’s early circulation, though incoming energy from a cold front could help it strengthen later in the week, per WUFT.
For Cedar Key and the rest of the Nature Coast, that uncertainty is the headline for now: nothing is imminent, but the setup bears watching into the weekend.
Flooding, not wind, is this week’s immediate risk
The more pressing concern across North Florida is a slow-moving cold front, the same system that dumped flooding rain on Texas late last week, which has been pushing rain across the Panhandle and is forecast to crawl across the peninsula through the week, according to WUFT.
A flood watch covering the area from Pensacola east to Jacksonville was extended Sunday evening and was set to run at least through Monday morning, with officials weighing whether to extend it further. The Weather Prediction Center placed the Panhandle under a slight risk of flash flooding, at least a 15 percent chance within 25 miles of any point, with a marginal risk, or at least 5 percent, stretching from Tallahassee eastward.
Rainfall totals matter here. Along and north of I-10, 24-hour totals were already running 2 to 5 inches, with another 2 to 6 inches forecast through Wednesday night. Over the full week, from Monday morning through Saturday morning, the Jacksonville area could see 5 to 7 inches, with isolated spots topping 10 inches. The Panhandle could add another 5 inches on top of weekend totals.
What it means closer to the coast
Central Florida, which includes the Nature Coast and Levy County, is forecast to see 2 to 4 inches of rain between Monday and Saturday, with isolated totals exceeding 5 inches where storms stall out. That’s a lighter total than North Florida is facing, but enough to raise local flooding concerns on low-lying roads and around the Suwannee and Waccasassa river systems if rain bands linger.
The front is expected to slow further and stall near Lake Okeechobee by Wednesday or Thursday, which would pull the heaviest rain chances south and away from this coast later in the week, though South Florida would see its own flooding risk build as a result.
Bottom line for this coast
Nothing in the Gulf has organized yet, and the near-term flood threat for Cedar Key and Levy County is modest compared with North Florida’s. But both stories are tied to the same slow-moving front, and the Gulf’s seven-day odds are expected to rise. Florida & Cedar Key News will continue tracking National Hurricane Center updates and any changes to flood watches that reach this coast.
