Delta Update, Nearly 450,000 Without Power in Louisiana, Texas and Mississippi

Hundreds of thousands were reported to be out without power across Louisiana, Texas and Mississippi after Hurricane Delta made landfall in Louisiana on Friday.

While Delta is now categorized as a post-tropical cyclone, it "continues to be a heavy rainfall threat," and flood/flash flood watches remain in place for areas in and around the southern Appalachians, the National Hurricane Center (NHC) reported Sunday.

Around 348,000 customers in Louisiana, 75,500 in Texas and 20,500 in Mississippi were reported to be without power, as of Sunday, according PowerOutage.us at the time of reporting.

Entergy had the largest number of affected customers in Louisiana, with over 142,000 reported to be without power on Sunday.

The company reported more than 483,000 power outages as the hurricane made landfall, the Entergy confirmed in a statement Friday.

"Customers may see extended power outages given the additional need for our crews to follow COVID-19 precautionary measures, hardest hit areas may experience outages for up to 10 days. In addition, restoration may be hampered by flooding, blocked access or other obstacles," Entergy said Friday.

Heavy rain and thunderstorms are expected to spread across the east coast through Monday, according to the National Weather Service (NWS) Weather Protection Center.

"The chance for flash flooding is particularly evident over the southern Appalachians on
Sunday and Monday. Rain is expected to spread into the northeast as post-T.C. [post-tropical cyclone] Delta interacts with a boundary to the north of it on Monday. Rainfall totals may reach two inches in isolated areas near Long Island," the NWS National Weather Protection Center noted Sunday.

The NWS noted: "Delta will continue to bring heavy rainfall and thunderstorms from the Central Appalachians to southern New Jersey.

As of Sunday, the post-tropical cyclone was reported to have maximum sustained winds near 30 miles per hour with higher gusts.

"Weakening is forecast during the next 24 hours, as Delta's surface low is expected to dissipate across the central Appalachians late Sunday night," the NHC reported Sunday.

Delta made landfall as a Category 2 hurricane, with a maximum wind speed of 100 miles per hour as it hit the Louisiana town of Creole on Friday.

The hurricane was downgraded to a tropical depression on Saturday, with a maximum sustained wind of 35 mph reported, as of 10 a.m. Central Time, according to NHC.

The winds in Mississippi were reported to be strongest in the west and southwest regions of the state, where emergency management officials reported downed power lines, snapped trees as well as damage to structures and cars, Mississippi's WTOK-TV reported.

The remnants of Delta are forecast to bring a total rainfall of three to six inches in the Appalachian region of northeast Georgia, the western Carolinas, and western Virginia, which "could lead to flash, urban, and small stream flooding, especially in areas of steep terrain. Isolated minor river flooding is possible," the NHC warned Sunday.

One to three inches of rain are projected for much of the rest of the Mid-Atlantic region, with locally higher amounts expected. "Localized flash and urban flooding are possible, but overall hydrologic impacts are expected to be minimal," the NHC noted.

"Moderate to major river flooring will continue across the Calcasieu and Vermillion river basins in Louisiana through much of next week.

"While a few brief/weak tornadoes are possible across the Carolinas today [Sunday]," the NHC noted.

Last week, President Donald Trump approved a request by Louisiana Gov. John Bel Edwards for a federal emergency declaration in advance of Hurricane Delta.

"We have been working with our federal and local partners to prepare for and quickly respond to this hurricane, even as we continue to recover from Hurricane Laura and manage the COVID-19 public health emergency," the governor said in a statement at the time.

Nic Hunter, the mayor of Lake Charles in Louisiana, which was badly hit by Hurricane Laura, noted: "Add Laura and Delta together and it's just absolutely unprecedented and catastrophic."

Delta is the 25th named storm of the latest Atlantic hurricane season and was the 10th named storm to hit the mainland region of the U.S. this year, breaking a record set in 1916, according to Colorado State University research scientist Phil Klotzbach.
