This is the Friday morning Storm Tracker desk for October 9, 2026. Overnight into this morning the organized severe window moved from a small Iowa hail threat to the northern Gulf Coast. The Storm Prediction Center 1300 UTC Day 1 convective outlook, issued 7:57 a.m. CDT, places a Slight Risk of severe thunderstorms across northern Florida, southeast Alabama, and southwest Georgia. The driver is Hurricane Isaias, still offshore. No convective watches are valid. The Weather Prediction Center holds a Moderate Risk of excessive rainfall over southern Alabama, the Florida Panhandle, and southwest Georgia.
Isaias has not made U.S. landfall. National Hurricane Center Intermediate Advisory 11A, corrected, at 7:00 a.m. CDT places the center near 27.0N 87.7W, about 245 miles south of Pensacola and about 170 miles south-southeast of the Mouth of the Mississippi River. Maximum sustained winds are near 110 mph, movement north-northeast near 15 mph, minimum pressure 958 mb. Hurricane-force winds extend outward up to 30 miles. Tropical-storm-force winds extend outward up to 185 miles. NHC says Isaias is on the cusp of major-hurricane strength, is likely to become a major hurricane this morning, and is expected to remain a dangerous hurricane at landfall this evening or tonight inside the warning area. Preparations in the storm-surge and hurricane warning areas should be completed within the next few hours.
These remain county- and ZIP-scale hazards until the core comes ashore. Verify with the National Weather Service for the specific county or ZIP before you roll. Conditions change with the next advisory.
What is live this morning
SPC lists no convective watches currently valid. The watch board’s most recent number, Severe Thunderstorm Watch 676, was a west-central Texas watch from the afternoon of September 30 and expired at midnight CDT that night. It is not a live product. The next Day 1 outlook is scheduled by 1630 UTC. Tornado potential is forecast to increase this afternoon and continue tonight, especially across the Florida Panhandle into southeast Alabama and southwest Georgia, as eastern rainbands spread north and low-level winds and storm-relative helicity strengthen. SPC also notes some enhancement to the wind field, including a convective influence, across southern Alabama near the evolving inverted surface trough late this afternoon into tonight.
The Slight Risk area covers about 25,034 square miles and roughly 1.97 million people. Larger centers named by SPC include Tallahassee, Dothan, Pensacola, Valdosta, and Panama City. The surrounding Marginal Risk covers about 42,289 square miles and roughly 3.98 million people, with larger centers including Jacksonville, Mobile, Savannah, Gainesville, and Albany. NHC tornado language is narrower in time: a tornado risk beginning late this afternoon and continuing tonight in coastal Alabama, the Florida Panhandle, and far southwest Georgia, then continuing Saturday across parts of eastern Alabama, the Florida Panhandle, Georgia, and the Carolinas.
Tropical warnings are the live watch equivalent this morning. A Storm Surge Warning runs from the Mouth of the Mississippi River to the Suwannee River. A Hurricane Warning runs from Ocean Springs, Mississippi, to the Bay/Gulf County line in Florida. Tropical Storm Warnings cover the Jefferson/Plaquemines Parish line in Louisiana to west of Ocean Springs, and the Florida coast east of the Bay/Gulf County line to the Aucilla River. A Storm Surge Watch continues from the Suwannee River to Yankeetown, Florida. Intermediate Advisory 11A corrected the surge values. If the peak coincides with high tide, water could reach 6 to 9 feet above ground from the Alabama/Florida border to Grayton Beach; 4 to 6 feet from Dauphin Island to the Alabama/Florida border and in Mobile Bay; 4 to 7 feet from Grayton Beach to Indian Pass; 4 to 6 feet from Indian Pass to the Steinhatchee River; 3 to 5 feet from Steinhatchee to the Suwannee and from the Mouth of the Mississippi to Dauphin Island; and 2 to 4 feet from the Suwannee to Yankeetown.
Hurricane conditions are expected in the hurricane warning tonight into early Saturday, with tropical storm conditions beginning later today. Tropical storm conditions are expected in the warning areas beginning in the next few hours from the 7:00 a.m. CDT advisory.
Overnight into this morning
The convective day that closed at 1159 UTC this morning did not produce a tornado or wind report on the SPC filtered log. It did produce hail. The overnight reports sit on yesterday’s Iowa Marginal Risk, not on the Gulf. SPC lists 1.00-inch hail 2 miles south of Sioux Center, Iowa, at 0226 UTC; 1.50-inch hail at Panora in Guthrie County at 0237 UTC; 1.00-inch hail at Orange City; 1.00-inch hail at Redfield in Dallas County at 0305 UTC; 1.50-inch hail at Ireton; 1.25-inch hail at Wall Lake in Sac County at 0320 UTC; 1.50-inch hail at Cherokee at 0337 UTC; 1.25-inch hail west of Norwalk in Warren County at 0401 UTC; 1.50-inch hail at Alcester in Union County, South Dakota, at 0532 UTC; and a measured 1.00-inch hail on the 200 block of Lloyd Street in Lake City, Calhoun County, at 0552 UTC. Those are preliminary local storm reports. They are the just-hit record from last night. They are not a continuing Iowa watch.
Thursday evening flash-flood products on the national summary were short-fused and have expired for this desk. Jacksonville issued a flash flood warning for east-central Nassau County, including Fernandina Beach, Yulee, and Amelia City, at 5:19 p.m. EDT Thursday, with 2 to 4 inches already down and another 1 to 2 inches possible, until 7:00 p.m. EDT. Honolulu issued a flash flood warning for Oahu at 10:21 a.m. HST Thursday after water over Kamehameha Highway on the North Shore, until 1:15 p.m. HST. Neither is a live warning this morning. Storm-surge warnings on the northern Gulf Coast from Thursday evening remain the standing coastal product and match the NHC warning.
Water pulse
WPC’s Day 1 Excessive Rainfall Outlook, updated 0825 UTC and discussed at 4:28 a.m. EDT, keeps a Moderate Risk of excessive rainfall in southern Alabama, the Florida Panhandle, and southwest Georgia, valid 12 UTC Friday through 12 UTC Saturday. WPC says numerous instances of flash flooding are likely, some significant, and that the outlook is consistent with the previous forecast. Heavier rain rates ramp up closer to landfall and after, as the strongest instability in the southeast quadrant reaches the coast. The flash-flood threat should increase markedly from late Friday afternoon into Friday night.
Two corridors matter. Inner-core and eyewall rain is the coastal problem in southern Alabama and the western Florida Panhandle, highest closest to the coast. Farther east, a training band along the instability gradient can sit about 200 miles east of the landfall point. WPC says that band has better access to instability and deep tropical moisture, can produce double-digit totals of 10 inches or more if it trains, and may hold the event maximum. The Moderate Risk was nudged slightly east, including the chance the band sets up east of Tallahassee at times, and extended into southwest Georgia at least 100 miles inland. Inland along the track into eastern Mississippi and central Alabama stays at Slight for now, because shear is increasing and the inland flash-flood reach depends on whether the core holds together. NHC rainfall through the weekend is 4 to 8 inches across southern Alabama, the Florida Panhandle and Big Bend, and southwest Georgia, with localized totals up to 15 inches in banding across the Panhandle and Big Bend. Much of the rest of the Southeast is forecast at 2 to 5 inches, with localized amounts up to 10 inches possible in the southern Appalachians and coastal Carolinas. River flooding is also expected, some of it significant.
Pulse table
| Region | Main threats | SPC / NWS level | Status this morning |
|---|---|---|---|
| Northern Gulf Coast (MS / AL / FL Panhandle) | Hurricane wind, storm surge, heavy rain tonight | Hurricane Warning; Storm Surge Warning; NHC Advisory 11A | Warnings up; center still offshore |
| FL Panhandle / SE Alabama / SW Georgia | Tornado in outer bands; damaging wind near the trough | SPC Slight; tornado risk late today into tonight | Live outlook, no convective watch |

| Eastern Mississippi / central Alabama | Inland rain along the track if the core holds | WPC Slight | Track-dependent |
| Iowa / southeast South Dakota | Hail to 1.50 inches overnight | Yesterday’s Marginal; reports only | Expired overnight pulse |
| Rest of the CONUS severe map | No general thunderstorm watch | No convective watch valid | Quiet outside the Gulf corridor |
Restoration read
This morning is still a prep window, and it is closing. The first exposure on the northern Gulf Coast is life-safety surge and wind, not a ticket count. Hurricane-force wind is a small radius, about 30 miles from the center, so structural wind damage will be concentrated near the landfall point inside the hurricane warning from Ocean Springs to the Bay/Gulf County line. Tropical-storm-force wind reaches much farther, out to about 185 miles, and that is the power, tree, and soft-roof radius that will show up well away from the eye. Surge of 6 to 9 feet above ground, if it verifies from the Alabama/Florida border to Grayton Beach, is the coastal floor and marina problem. It is not a uniform flood across the whole warning.
Water is the broader restoration pulse, and it is offset from the center. WPC is explicit that the training band east of landfall, on the order of 200 miles east, can hold the rainfall maximum. Crews that staff only the landfall pin will miss the flash-flood ground in the Florida Big Bend, around Tallahassee, and into southwest Georgia. Saturated roads, underpasses, and small creeks are the overnight into Saturday problem. River flooding follows. Iowa hail is a closed overnight note: roof and vehicle checks in Guthrie, Sioux, Sac, Cherokee, Dallas, Warren, and Calhoun counties, and at Alcester, South Dakota, not a new dispatch.
Do not treat a Slight Risk as a watch. SPC has not issued a tornado watch yet. The tornado window in NHC language opens late this afternoon in coastal Alabama, the Panhandle, and far southwest Georgia. If a watch goes up on the 1630 UTC outlook cycle, that is the afternoon desk’s update, not a fact this morning.
Looking ahead
Landfall is forecast tonight or early Saturday inside the hurricane warning. After landfall, gusty winds are expected well inland over the Southeast as the wind field grows in the trough interaction. Saturday’s tornado threat shifts across eastern Alabama, the Florida Panhandle, Georgia, and the Carolinas. Rain of 2 to 5 inches, locally 10, reaches the southern Appalachians and coastal Carolinas through the weekend. The next complete NHC advisory is scheduled for 10:00 a.m. CDT. The next SPC Day 1 outlook is scheduled by 1630 UTC.
