SHORT TERM
(This evening through Thursday night)
Issued at 1203 PM CDT Wed Sep 11 2024
Hurricane Francine continues to move generally northeast toward the eastern portions of Vermillion Bay. Landfall should be around sunset this evening and the storm will continue to move north and east into southern MS by late tonight and early Thursday morning.
Overall, no impact changes from the overnight package with the highest winds residing along and west of I-55 and south of I-12.
Additionally, heavy rainfall will continue to spread over the region increasing the flash flood potential across the region.
Otherwise, a dry slot seems to have developed just east of the center which is likely going to further entrain into the system as it continues to move north and east...so any additional strengthening of the hurricane will be extremely limited. With the dry air entrainment, think that some of the outer bands will start to rotate leading to a higher tornado potential, especially north and east of the center of Francine. Storm surge will also begin to increase with max surge generally along the Terrebonne coast. That said, as water piles into the tidal lakes remember it will likely take time especially with onshore flow continuing for some of the water to drain on the backside of the storm, which may result in high waters for a couple of high tide cycles.
The storm as it pulls northward away from the region, expect dry conditions to take over leading to much better weather going into the day on Thursday. Dry northwesterly flow will set up with much of any residual rain/storms move east and north away from the CWA (Frye)
LONG TERM
(Friday through Tuesday night)
Issued at 1203 PM CDT Wed Sep 11 2024
Dry northwesterly flow will continue into the start of the weekend as we remain on the western periphery of the upper level trough over the southeast U.S. A weak vort/mid level impulse will develop and move southward within this flow, which should bring with it some increased POPs by Sunday and into the start of the new workweek. Temperatures will again increase starting Friday and into the weekend and beyond, however, with the upper trough in place, expect temperatures to only climb into the upper 80s or lower 90s. (Frye)
AVIATION
Issued by National Weather Service Jacksonville FL (00Z TAFS)
Issued at 707 PM CDT Wed Sep 11 2024
Hurricane Francine has made landfall in the Terrebonne Parish and is progressing north-northeastward across the TAF sites tonight.
Ceilings at all airfields are either below, or soon to be below, IFR conditions. Low level wind shear will be an issue at all stations through 12/12 utc. Have indicated IFR conditions in the prevailing groups. The eye is currently over KHUM with much of the heavier rain done for this site. The eyewall is anticipated to move near KMSY, KNEW, and KHDC potentially bringing gusts of 50-60 kts. Elsewhere, heavy showers with embedded thunderstorms and sustained winds of 25-35 kts and gusts of 30-40 kts continue overnight.
Behind the eye, winds become west- southwesterly. Wind and rain will gradually diminish overnight with rain tapering off from south to north from 12/06 utc - 12/12 utc. A low stratus/cumulus deck between 1-1.5 kft will move in from off the Gulf behind the system.
MARINE
Issued at 1203 PM CDT Wed Sep 11 2024
Dangerous marine conditions continue across the local waters as Hurricane Francine moves through the outer waters south of Terrebonne Bay. The hurricane will make landfall later this afternoon or early evening. Dangerous conditions will persist through the overnight and into early Thursday before improvement begins as the storm moves more to the north and east away from the region. (Frye)
