SHORT TERM
(Today through Friday night)
Issued at 440 AM CDT Wed Sep 11 2024
Hurricane Francine currently sits in the northwest Gulf, due south of Cameron, LA by roughly 170 miles. It is currently a 90 MPH Category 1 hurricane and is expected to strengthen slightly more into a strong Category 2 hurricane with 100 MPH winds before landfall along Vermilion Bay later this afternoon or evening. Expect conditions to consistently degrade after sunrise for those along and east of HWY 167, and most primarily for those along the Atchafalaya Basin.
A tight gradient of rainfall should develop with those along and west of HWY 167 seeing very light rainfall and low rainfall totals today/tonight.
Francine will move to the northeast rather quickly and improving conditions will develop into Thursday morning. Some lingering light rainfall and breezy conditions can be expected for much of Louisiana into Thursday morning; Thursday afternoon for central and north Louisiana. Strong northwest flow around the storm center in north Mississippi will send drier air back down into central and south Louisiana by Friday morning, bringing about a pleasant start to the weekend.
11/Calhoun
LONG TERM
(Saturday through Wednesday)
Issued at 440 AM CDT Wed Sep 11 2024
The mid to upper level pattern will remain west to west northwest through the weekend with no significant moisture or lift to generate any precipitation. Monday through Wednesday, limited low level moisture may generate some isolated afternoon showers, but chances remain less than 20%.
Temperatures through the period will see highs in the upper 80s to lower 90s, with lows in the upper 60s to lower 70s each day.

AVIATION
(12Z TAFS)
Issued at 719 AM CDT Wed Sep 11 2024
Conditions will only deteriorate this morning as Hurricane Francine marches closer to the Louisiana coastline. Outer banding is moving over Alexandria, bringing about gusty winds and heavy rainfall. This band will move to the north in the next hour with the terminal experiencing a break in hazardous conditions until about 18z when rain and gusty winds return.
Coastal terminals will experience more impacts from Francine, specifically Acadiana Terminals. BPT and LCH should remain fairly dry today with only on and off heavy rainfall. Strong north gusts can be expected as the cyclone passes this afternoon. Rain chances should fall off after 06z.
Rainfall is moving into Acadiana ahead of Hurricane Francine.
Francine is expected to strengthen into a Category 2 Hurricane with 100 MPH winds before moving onshore near Vermilion Bay this afternoon or evening. This places LFT and ARA nearest to the area of strongest winds and gusts, with directional and speed shear off the surface. Tropical Storm Force winds/gusts are expected, Hurricane Force winds/gusts possible, in the afternoon and early evening hours. Heavy downpours are expected for much of the day with low VIS and IFR ceilings. Conditions will start improving after 08Z.
