Added: 2026-05-26

[00:00:01]LABOR DAY, THROUGH THE BLUE STAR MUSEUMS PROGRAM.

[00:00:05]TIME NOW IS 548.

[00:00:06]TIME ONCE AGAIN TO GET ANOTHER CHECK FOR YOU OF YOUR FORECAST ON A WDSU FIRST WARNING WEATHER IMPACT DAY.

[00:00:13]HEY, GOOD MORNING EVERYBODY.

[00:00:14]SO WE ARE STARTING OFF ON THE MOSTLY CLOUDY SIDE, BUT AT LEAST MOST OF US ARE DRY.

[00:00:19]NOW YESTERDAY WE HAD A LOT GOING ON.

[00:00:20]THAT IS NOT THE CASE AT ALL FOR THIS MORNING.

[00:00:22]MOST OF OUR ACTIVITY IS GOING TO GET STARTED LITTLE LATER ON FOR TODAY, BUT WE ARE STILL DEALING WITH QUITE A BIT OF MOISTURE INTO THE AREA, AND THIS IS GOING TO CONTINUE FOR THE REST OF THE WEEK.

[00:00:31]EVENTUALLY, THIS IS ALL GOING TO PUSH TO THE EAST AS WE ARE GETTING DEEPER INTO THE WEEK.

[00:00:36]IN THE MEANTIME, LET’S TALK ABOUT WHAT WE’VE SEEN OVER THE PAST 24 HOURS.

[00:00:39]I’M SHOWING YOU THE RAINFALL TOTALS BECAUSE WE DO HAVE EVEN MORE ON THE WAY.

[00:00:43]SO ESPECIALLY OVER IN MISSISSIPPI, IT WAS VERY RAINY, VERY BUSY.

[00:00:48]ALMOST FOUR INCHES REPORTED UP IN POPLARVILLE.

[00:00:50]AGAIN, THIS IS OVER THE PAST 24 HOURS.

[00:00:52]SO THESE NUMBERS ARE GOING TO GO DOWN SOME.

[00:00:54]BUT LOOKING AT FOUR TO ABOUT SIX INCHES OUT NEAR KILN YESTERDAY.

[00:00:57]SO AS FAR AS WHAT’S HAPPENING WITH THE RIVERS, JUST BECAUSE OF ALL THE RAIN WE’VE GOTTEN, SOME OF THEM ARE STARTING TO SWELL.

[00:01:03]SO WE’LL BE WATCHING THIS VERY CLOSELY AS WE’RE HEADING INTO THE NEXT COUPLE OF DAYS.

[00:01:07]IN THE MEANTIME, LOOKING AT A FLOOD WATCH IN EFFECT, NOTICE IT’S NOT FOR ALL OF US, FOR ABOUT HALF OF US, WE’RE EXPECTING TO SEE THAT UNTIL 7 P.M. FOR TODAY.

[00:01:16]WE DO HAVE A COUPLE OF SHOWERS ON RADAR RIGHT NOW OVER LAKE CATHERINE GALVEZ PEARLINGTON HEADING ON UP.

[00:01:22]AGAIN, THESE ARE LIGHT IN COMPARISON TO THIS TIME YESTERDAY AND THE COUPLE STARTING TO POP UP TO JUST SOUTH OF LAFAYETTE, SEEING SOME OUT NEAR POINT CELESTE AND OVER THE MARSH AREA.

[00:01:31]BUT AGAIN, MOST OF US GOING TO GET OUT THE DOOR, PROBABLY JUST FINE AND LOOKING JUST TO THE SOUTH OF GRAND ISLE, ON THE OTHER SIDE OF THE MOUTH OF THE MISSISSIPPI RIVER, SOME STARTING TO GROW, NOT SEEING ANY LIGHTNING REPORTED JUST YET, BUT WE’RE WATCHING THAT BECAUSE THINGS ARE ABOUT TO GET BUSY AS WE HEAD INTO THE NEXT FEW HOURS.

[00:01:48]SO THE MORNING COMMUTE FOR MOST OF US TRYING TO GET TO WORK TODAY, I THINK YOU SHOULD BE FINE.

[00:01:53]BUT ONCE WE GET TO ABOUT 1112 TODAY, THAT’S WHEN WE’LL START TO SEE THESE GROW.

[00:01:57]AND AGAIN, YOU CAN SEE WHY WE’RE LOOKING AT THE FLOOD WATCH FOR ABOUT HALF OF THE AREA.

[00:02:01]LOOK FOR MOST OF THE RAIN IS CONFINED TO FOR THE FIRST HALF OF THE DAY.

[00:02:05]THEN ONCE WE GET TO THE AFTERNOON ON INTO THE EVENING, IT DOES SPREAD TO EVERYBODY ELSE.

[00:02:09]AND THIS IS WHEN WE COULD SEE THAT HEAVY RAIN FALLING SO WE COULD GET SOME LOCALIZED STREET FLOODING, AS WE COULD SEE SOME RAIN OVER THE SAME SPOT IN A SHORT AMOUNT OF TIME.

[00:02:17]SO JUST BE ON THE LOOKOUT FOR THAT.

[00:02:18]LOOKING AT THAT SAME THING FOR TODAY.

[00:02:20]SO AS FAR AS HOW MUCH RAIN WE COULD SEE FOR TODAY INTO TOMORROW, ABOUT 1 TO 2IN POSSIBLE FOR US.

[00:02:26]THIS IS NOT TAKEN INTO ACCOUNT ANY OF THE SPOTS THAT COULD SEE THOSE VERY HEAVY DOWNPOURS.

[00:02:31]AND THEN FOR TOMORROW, ALSO LOOKING AT THE THREAT FOR SEEING SOME FLASH FLOODING, SEEING THAT SAME THING AS WE HEAD INTO OUR THURSDAY AS WELL.

[00:02:38]SO THIS CONTINUES FOR THE REST OF THE WEEK FOR THE NEXT SEVEN DAYS, WE’RE LOOKING AT ABOUT 2 TO 3, MAYBE FOUR PLUS MORE INCHES OF RAIN.

[00:02:47]AGAIN, DOES NOT SHOW ANY OF THE SPOTS THAT MAY END UP WITH THOSE VERY HEAVY DOWNPOURS.

[00:02:52]THAT COULD LEAD TO ISSUES.

[00:02:54]NOW, LOOKING AHEAD TO WEDNESDAY, WEDNESDAY MORNING, AS OF RIGHT NOW, LOOKS LIKE IT MAY END UP BEING OKAY.

[00:02:59]WE’RE GOING TO SHIFT OUR ATTENTION TO THE AFTERNOON.

[00:03:01]SO KIND OF THE SAME STORY AS TODAY AFTERNOON WILL START TO GET VERY BUSY FOR US, ESPECIALLY INTO THE EVENING.

[00:03:07]THAT’S WHEN WE COULD SEE MOST OF THAT ACTIVITY.

[00:03:10]HERE’S A LOOK AT THE REST OF THE WDSU FIRST WARNING.

[00:03:12]SEVEN-DAY FORECAST MORE DAYS OF RAIN, MORE IMPACT DAYS ALL THE
