KEY MESSAGES

Updated at 518 AM CDT Sat Oct 10 2026

- All Hurricane, Tropical Storm and Storm Surge Warnings have been cancelled.

- A Coastal Flood Advisory will be in effect overnight for counties and parishes that were previously in the Storm Surge Warning. This is generally coastal areas from the mouth of the Mississippi River to the Alabama state line. Inundation of 1 to 3 feet above normally dry ground will be possible somewhere within flood prone areas in the advisory through Saturday morning.

- Small Craft Advisories are in place for all coastal waters through mid-morning Saturday as conditions slowly improve.

- Much above normal temperatures will return with high temperatures approaching 90 degrees on Sunday, and continuing through much of next week with little or no precipitation.

SHORT TERM

(Now through Tuesday) Issued at 1027 PM CDT Fri Oct 9 2026

Hurricane Isaias will move quickly north through Alabama the remainder of the night while weakening. A few rain showers can't be ruled out through mid-morning Saturday, but rainfall totals should be light. Winds will subside to 10 to 20 mph by sunrise, and then go calm overnight as high pressure moves into the area. High pressure will become centered over the area for Monday and Tuesday, with mostly dry weather expected beyond this morning.

Clouds will decrease during the day Saturday, with highs getting into the lower 80s. With full sunshine Monday and Tuesday, much above normal high temperatures will return with most areas seeing highs from the mid 80s to perhaps the lower 90s in a few areas. Dry air will be in place, and with light winds expected during nighttime hours, lows the next few nights could fall into the 50s across the northern half of the area. Lake Pontchartrain's 80 degree water could hold the New Orleans area in the 60s or closer to 70.

Coastal Flood Advisory is replacing the Storm Surge Warning through the current high tide cycle as some minor inundation could still occur.

LONG TERM

(Tuesday night through Friday) Issued at 1027 PM CDT Fri Oct 9 2026

High pressure at the surface and aloft will remain pretty close to the local area through at least Thursday and probably Friday. A strong storm system moving through the Great Lakes late in the workweek could send a cold front southward toward the area by Friday. Even at that point, conditions don't look favorable for precipitation.

Much above normal high temperatures will continue through the workweek, with highs in the lower 90s possible across much of the area through at least Thursday. If those temperatures are achieved, there may be some high temperature records broken or tied. If the cold from moves through the area next weekend, highs will fall off several degrees. Overnight lows should mainly be in the 60s.

AVIATION

(12Z TAFS) Issued at 518 AM CDT Sat Oct 10 2026

Mostly VFR conditions today with some residual gusty northerly winds possible. After sunset the winds should decrease below 10 knots. Sunday morning, BTR is signaling some lower VIS, which needs to be watched in subsequent updates. (Frye)

MARINE

Issued at 1027 PM CDT Fri Oct 9 2026

Marine conditions will improve as Isaias continues to move northward away from the coast while it weakens. Tropical Storm and Hurricane Warnings were dropped, and replaced by Small Craft Advisories that will run through mid to late morning. It may take into the afternoon for seas to lower to a comfortable level for operations, but from Sunday onward, winds should remain below 15 knots across the waters until perhaps Thursday night or Friday of next week. This should keep seas in the 1 to 3 foot range, or less.
