new orleans – The storm system that flooded the Pacific Northwest and California on Thursday is now moving through the Southeast with heavy rain and thunderstorms.
On Friday, the Storm Prediction Center issued a severe thunderstorm warning for much of central Texas, with multiple tornadoes reported.
Fewer severe storms are expected as instability eases around the Gulf Coast over the weekend, but heavy rain could especially cause problems for the ongoing Mardi Gras festivities.
Heavy rain threatens flooding, Mardi Gras parade schedule adjusted
The National Oceanic and Atmospheric Administration's (NOAA) Weather Prediction Center highlighted parts of southeastern Texas, Arkansas, Louisiana, and Mississippi as being at increased risk of excessive rainfall and flooding.
That region includes Baton Rouge and New Orleans, where Mardi Gras celebrations are held for a month Saturday.
More than 20 Mardi Gras parades are scheduled in New Orleans from Friday through Sunday, and the parade into Saturday evening is likely to be rainy, with 3 inches of rain expected to fall in wind gusts up to 35 mph. has been done. In fact, some parades had to adjust their schedules.
“Five crew members on the New Orleans route were forced to depart two hours early, and the sixth crew member was actually delayed until Sunday,” FOX Weather meteorologist Brandi Campbell said Friday from New Orleans. reported. He said, “In collaboration with the New Orleans Police Department, crews have decided to reduce the number of bands and other marching elements within the force.”
About 15 minutes away in Metairie, Louisiana, the only parade scheduled for Saturday was the Magical Krewe of the Mad Hatters. But they plan to move behind the Atlas Parade on Sunday after hearing from meteorologists that they would have been hit by bad weather if they hadn't changed the parade.
Joey Lacoste of the Mad Hatters Magical Crew told FOX Weather, “When you see a thunderstorm raining down on a parade, it's the emptiest feeling.” “You know, the heart is at your feet. So we were really concerned. Plus, there's a safety issue here because there's a big float that could attract lightning. Plus, thunderstorms. No one wants to sit inside and watch a parade.”
Blowtorch weather will continue through the last month of winter, NOAA says
How much rain will it fall?
Forecast models are predicting widespread rainfall of 1 to 2 inches across the South, with some areas potentially seeing more than 3 to 4 inches. Some Mississippi counties are already under flash flood watches.
More than a dozen watershed gauges along the lower Mississippi River are already at flood stage due to heavy rains in January.
Several storms have passed through the area over the past three weeks, reducing precipitation by 1 to 2 feet.
The rains have reduced the area suffering from extreme and unusual drought by more than half, but 88% of Louisiana and 84% of Mississippi remain abnormally dry.
By Tuesday morning, the entire storm system is expected to move off the East Coast, but an active jet from the south during an El Niño event will reduce the amount of precipitation impacting the Gulf Coast. It is expected that this possibility will increase.
