Impact and Alert Days: Flood risk increases across Louisiana this weekend
We saw some pretty heavy downpours earlier today across southeast Louisiana. Yesterday, *** majority of the rain was across the South Shore. Today, majority of it was across the North Shore. In fact, some of the most heaviest rain was located just north of Covington near Saint Benedict, where some spots saw anywhere between 2 to 3 inches of rain. Another spot saw over 6 inches of rain. It’s 0.5 ft of rain with just in *** span of *** few hours, and at this. Point, the radar is dry. There’s nothing worth tracking, and temperatures are still *** little bit on the cooler side since that rain cooled air came in earlier today. North Shore in the mid to upper 70s, South Shore in the low 80s right now, and that’ll likely stay that way through the rest of the night and into tomorrow morning. Speaking of tomorrow morning, we got our first round of downpours and thunderstorms coming in as early as 4 a.m., crossing the. Bayou parishes that’ll slowly lift northward into the northern portion of the South Shore just south of Lake Pontchartrain over the Orleans Metro as early as 9 p.m. or excuse me, 9 a.m. and this is 11:30 a.m. we got this another wave of rain and heavy downpours and thunderstorms coming in. I don’t think we’ll see any significant or any severe weather at all tomorrow. I think the main threat will be the amount of rain we see, the flood. Like we saw today in the North Shore and yesterday in the South Shore, so we’ll keep an eye out on that. At this point we’ve already seen multiple waves of downpour move across the South Shore and as early as 11 a.m. the North Shore is gonna get their fair share of rain too. This is throughout the rest of the evening. By 8 o’clock things finally start to clear out and by 11 o’clock we are bone dry. Now here’s *** look at the hour by hour parish by parish, uh, chart. Here 4:00 a.m. to 11:00 a.m. for our bayou parishes. This includes Terrebonne Parish and parts of Plaquemine Parish, La Fouche Parish and Southern Jefferson Parish and the Orleans Metro, Northern Jefferson Parish, Saint Bernard Parish, Saint John’s, Saint James, and Saint Charles Parishes. That’s you guys between 8:00 a.m. and 2:00 p.m. and then 10:00 a.m. to 5:00 p.m. for the North Shore Tangipahoe, Saint Tammany Parish. That’s you guys also Washington Parish, Pearl River County, Mississippi, and. Also Hancock County, Mississippi, that’s you guys too. Heavy rain is something everybody will see which could lead to some flooding in some spots. We only saw *** couple of spots this weekend, but I think we could see *** little bit more spots with easily over 3 to 4 inches of rainfall which could cause some major flooding. Gusty winds and water spouts can’t be ruled out, but not looking all that likely. So again, this is the average rainfall. I think the North Shore closer to 1.5, *** little bit closer. To 2 inches for the South shore, but that’s the average again, locally heavy spots could easily climb to 3 to 4 inches, if not more than that. And that’s why the storm prediction Center, the weather prediction Center, has put out *** level 2 risk for flooding, *** slight risk for the entirety of Southeast Louisiana and Southern Mississippi too, because of that risk for flooding. Now rain chances will drop in the middle of the work week Wednesday, Thursday, and Friday. Most people will stay dry. Saturday and Sunday. Typical summertime pattern for this time of year and we’ll climb only to the upper 80s and low 90s in terms of that heat index tomorrow because of all that rain cooled air and get this, it’s gonna feel like the low 70s across the North Shore as early as 6:00 a.m. Tuesday morning. Got *** cold front coming in from the north. It’s bringing in *** little bit drier air that allows us to cool more efficiently, especially across the North Shore, and so it’s *** little bit more comfortable but still warm, humid with *** summertime pattern through next weekend. All righty, Jay, thank you. Coming up next.
