Active Weather
The National Weather Service public alert feed, read at about 1 AM Eastern this morning, counts eight active alerts in North Carolina, three in Mississippi, two in Florida, and one each in Georgia and South Carolina. Alabama, Kentucky, and Tennessee carry none.
The product names behind those counts could not be resolved this run. The feed returns counts by state in its summary view and the follow-up query failed, so this brief names the states and the numbers rather than guessing at types. Entering your county at weather.gov returns the exact product and its expiration in a few seconds, and that is the right move if you are in one of the five states named above.
The Weather Prediction Center's excessive rainfall discussion, issued at 12:58 AM Eastern today, holds a marginal risk of excessive rainfall over portions of the Southeast through this morning, and returns a marginal risk to parts of the region on Wednesday. Marginal is the lowest of four levels. It means scattered storms could drop enough rain fast enough to cause isolated flooding in poor-drainage spots, not that widespread flooding is expected.
The Storm Prediction Center's overnight outlook, issued at 7:40 PM Central Sunday, draws no severe thunderstorm risk area in the Southeast. Its daytime update for Monday issues later this morning.
The Atlantic basin holds no tropical cyclones as of the National Hurricane Center's 5:01 AM Eastern update.
Infrastructure
No large wildfires are burning in the eight states, according to the National Interagency Fire Center situation report dated Sunday September 6 at 7:30 AM Mountain time.
That same report puts the national wildfire preparedness level is 4 on a five-step scale, according to the National Interagency Fire Center situation report dated Sunday September 6 at 7:30 AM Mountain time. That report counts 75 uncontained large fires nationally, with 53,165 fires and 8,302,657 acres burned so far this year, running at 125 percent and 158 percent of the ten-year average.
No grid emergencies or water system disruptions are reported across the region. The Federal Emergency Management Agency's declarations page could not be read this run, so this brief reports no change either way on open declarations.
Public Health
No heat alerts, air quality alerts, or boil-water advisories were identified for the eight states. As noted above, the alert types behind the North Carolina, Mississippi, Florida, Georgia, and South Carolina counts were not resolved, so this reflects what was found rather than a guarantee.
The Centers for Disease Control and Prevention's Health Alert Network archive could not be read this run, so this brief makes no claim about national health advisories in either direction.
Watch Item
The rainfall pattern is the thing to keep an eye on rather than any single day inside it. The Weather Prediction Center has the Southeast inside a marginal risk today, out of it tomorrow, and back inside a marginal risk on Wednesday. Repeated low-end rain days on ground that is already wet is how flooding happens in places that would shrug off any one of those days alone.
The household version of that is simple and does not require watching a forecast. If your commute crosses a low spot, a dip under a rail bridge, or a creek crossing, know now which alternate route avoids it. Do not drive into water across a road. That is the National Weather Service's Turn Around, Don't Drown guidance, and it is the single piece of flood advice that changes outcomes most, because the majority of flood deaths happen in vehicles.
The wider seasonal frame is that September is the peak of the Atlantic hurricane season and the basin is currently empty with nothing in the outlook. For the coastal Carolinas, Georgia, and Florida, a quiet week in the first half of September is time, not luck, and time is the only thing that makes storm preparation inexpensive.
The specific work that pays: fuel in the vehicle before it is needed rather than after, a written list of what is in the freezer, and a plan for prescriptions that assumes the pharmacy is closed for three days. None of that requires a storm to justify it, and none of it can be done in a hurry.
