Top Stories

WEST MONROE, LA. – (10/09/20)

7 P.M. (Friday) Update:

Delta continues to push inland per the latest National Hurricane Center update. It still holds at Category 1 strength, with winds at 90 M.P.H. and moving North-Northeast at 14 M.P.H. Many of the details in the 6 P.M. update are still valid, with conditions continuing to deteriorate through the evening.

6 P.M. (Friday) Update

Delta has officially made landfall near Creole, Louisiana with maximum sustained winds near 100 mph. The storm is expected to weaken rapidly as it moves inland through the night. Widespread rain will continue through the ArkLaMiss through early Saturday, but winds will also begin to increase later tonight. Closer to midnight, expect sustained winds of 25-35 mph along and east of the storm’s center. Wind gusts up to 50 mph will be possible, with more isolated gusts up to 60 mph.

4 P.M. (Friday) Update

Delta is noticeably weaker as it approaches the southwestern Louisiana coastline. The eyewall structure is collapsing, cloud tops are warming, and the overall structure of the storm is beginning to break. Nevertheless, Delta will still be a dangerous hurricane when it makes landfall in the next few hours.

Forward motion has become more north-northeasterly and has increased slightly in forward speed. A general path over the southeastern sections of the ArkLaMiss is still expected late tonight through early Saturday.

While Delta is expected to be a tropical storm in the ArkLaMiss, most of our tropical storm force winds will likely come in the form of gusts. With a significant weakening trend expected after landfall, Delta’s wind field should become much smaller rather quickly. That said, sporadic power outages will still be possible later tonight, especially in areas south and east of the storm’s center.

10 A.M. Update

Not too much has changed with Hurricane Delta as it remains a category 3 hurricane with max sustained winds of 115 mph moving north at 13 mph. It is still on track to make landfall later today as a category 2 hurricane along the south/west Louisiana Coast.

Expected arrival of heavy rain and gusty winds for the ArkLaMiss is still late Friday into early Saturday morning. By then, Delta will most likely weaken to a tropical storm.

5 A.M. Update

Delta remains a major category 3 hurricane this morning with max winds of 120 mph. It is still anticipated to weaken back to a category 2 before making landfall late Friday afternoon/early evening along the Louisiana Coast.

We should still expect impacts here in the ArkLaMiss as Delta will most likely move through as a tropical storm. This means that some areas could see winds at 39 mph or greater with gusts up to 45-50 mph along with periods of heavy rainfall. This storm will continue to weaken as it moves through Saturday morning off to the north and northeast.

4 P.M. UPDATE

Delta is once again a major hurricane with maximum sustained winds near 115 mph. The forecast cone from the National Hurricane Center remains unchanged in its general thinking, with landfall expected Friday evening along the southwestern Louisiana coastline.

As earlier stated, impacts in the ArkLaMiss are expected. Wind gusts of up to 50 mph and periods of heavy rainfall will be possible along and east of Delta’s center as the storm moves inland. Impacts will lessen for areas farther north and west.

Preparations need to continue through early tomorrow ahead of deteriorating weather conditions late Friday afternoon through Saturday morning. An updated graphical outlook of the forecast can be found in the gallery below.

10 A.M. UPDATE

Hurricane Delta remains a category 2 hurricane with max winds of 105 mph moving northwest at 14 mph. It is still on track to strengthen back to a category 3, but will most likely weaken before landfall once it reaches the cooler waters closer to the Louisiana Coast. Projected landfall for the Louisiana Coast looks to be by Friday late afternoon.

Arrival for the ArkLaMiss is still on track for late Friday night and into early Saturday morning. Expect heavy rainfall and winds from 30-40 mph with gusts up to about 40-45 mph.

WEST MONROE, La. — (10/7/2020) Hurricane Delta has emerged in the southern Gulf of Mexico noticeably weaker, spending much of the day over the Yucatan Peninsula. The storm is expected to reorganize and develop into a major hurricane for a brief period on Friday morning.

After that, Delta will encounter shear from an approaching trough while moving over cooler waters near the northern Gulf coast. The storm should begin to weaken slightly before landfall on Friday afternoon.

The storm will continue to move quickly inland, perhaps moving over the southern ArkLaMiss parishes Friday night/Saturday morning as a low-end tropical storm. Impacts in our area will be greatest for areas along and east of Delta’s landfalling center.

Tropical storm force wind gusts will be possible, especially along the Mississippi Valley, Friday night into early Saturday morning. Some sustained winds up to 35 mph will also be possible, generally for areas along and east of Highway 165. Winds will be capable of downing trees and causing sporadic power outages.

Due to the storm’s quick forward motion, widespread flooding is not expected to be a major concern. Most of the ArkLaMiss can expect rain totals in the 3-5″ range, with some areas farther eastward seeing over 6″. Flash flood watches are in effect along the Mississippi Valley through early Saturday.

ArkLaMiss Rainfall Forecast (through Saturday afternoon)

Isolated tornadoes will be possible immediately along the coast, but is not a primary threat in our area. While an isolated tornado can’t be ruled out, a significant threat isn’t likely for the ArkLaMiss. We will continue to monitor this scenario through the duration of Delta’s landfall.

Residents are urged to prepare for gusty winds and periods of heavy rain through the day Friday into early Saturday. Stay updated with the latest weather information as Delta approaches the coast this weekend. Subtle changes with the storm’s track could lead to more significant impacts in any given area.
