The Weather Prediction Center places Florida under a marginal risk of excessive rainfall today, the lowest of its four levels. The concern is rain rate rather than storm total. Forecasters expect thunderstorm rainfall rates of two to three inches an hour, and the center's discussion specifically flags urban areas as where that becomes a problem, because pavement and storm drains cannot take water in that fast.

In plain terms: a Florida afternoon storm today could put several inches on a neighborhood in an hour and briefly turn low lying streets and underpasses into standing water. This is not river flooding and it is not a multi-day event. It is the kind of flooding that resolves within a few hours of the storm moving off.

The household action here is narrow and it is the one that matters. Do not drive into water across a road. The National Weather Service's long standing guidance on this is Turn Around, Don't Drown, because the depth is not judgeable from a driver's seat and the roadbed underneath may already be gone. Every other flood precaution is secondary to that one.

No severe thunderstorm risk area is drawn over the Southeast today. Alabama, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee are outside both the severe outlook and the excessive rainfall outlook. Expect a typical early September pattern in those seven states, hot and humid with scattered afternoon storms.

Mississippi remains under a presidential major disaster declaration issued in early August, including a separate designation covering public assistance for local government infrastructure repair. Federal recovery assistance is open to eligible applicants in the designated counties. If your household was affected and has not applied, check the deadline, because these windows close on a published date.

No active power grid emergencies, water system disruptions, or wildfires of size are reported across the eight Southeast states.

The National Interagency Fire Center's September 1 situation report lists no large uncontained fires in the Southern geographic area. Regional fire activity is at a seasonal low, which is normal for a humid early September.

No active public health advisories specific to the Southeast. No air quality alerts are posted across the eight states today.

Heat remains the region's routine early September health consideration. The people most affected are older adults, young children, anyone working outdoors, and anyone without reliable air conditioning. Checking on a neighbor who fits one of those descriptions is the single most useful thing most households can do about it.

The National Hurricane Center's outlook issued September 1 says tropical cyclone formation is not expected in the Atlantic basin over the next seven days. For the Southeast in the first week of September, this is the headline of the whole brief. This region sits at the peak of its hurricane exposure right now, and the basin is quiet for the coming week.

That is a window, and windows close. The climatological peak of the Atlantic season falls on September 10, and the second half of the month stays active in most years. A clear seven day outlook today says nothing about the week after next.

So use it. The list is short and every item is easier this week than it will be during a watch. Confirm you have stored water and that it has been rotated. Confirm your flashlights work. Know your evacuation zone if you are on the coast, which is a specific letter or number assigned by your county, not a general sense of being near the water. If you keep a generator, start it now and confirm it runs, and follow the manufacturer's instructions for where it may be operated.

Tropical Storm Edouard came ashore in Louisiana on September 1 and its remnant moisture is working inland across the South Central region. Whether any of that moisture swings east into Mississippi, Alabama, or Tennessee later this week is worth watching, though no product currently forecasts it.
