UPDATES ON THAT. DEVELOPING STORY. IN THE MEANTIME, RIGHT NOW LET’S TURN OUR ATTENTION ONCE AGAIN TO YOUR WDSU FIRST WARNING WEATHER FORECAST. ON AN ALERT DAY. YEAH. GOOD MORNING EVERYBODY. AS YOU’RE WAKING UP ON THIS MONDAY, HERE’S WHAT YOU NEED TO KNOW FOR THE WEEK. WE ARE LOOKING AT A FLOOD POTENTIAL. THIS IS GOING TO BE ALL WEEK LONG TO SOME HEAVY RAIN GOING TO BE MOVING INTO THE AREA, HANGING AROUND THE AREA FOR QUITE SOME TIME. WE’RE ALSO STILL WATCHING THE TROPICS VERY CLOSELY, STILL LOOKING AT A LOW CHANCE FOR SEEING DEVELOPMENT. ZERO CHANCE AS WE HEAD INTO THE NEXT 48 HOURS, BUT WE’RE STILL WATCHING AS WE GET TO THE MIDDLE TOWARDS THE END OF THE WEEK, WE’LL HAVE TO WATCH IT VERY CLOSELY. LET’S GET TO RIGHT NOW. I GOT A LOT GOING ON TO HEAD OUT THE DOOR, ESPECIALLY IF YOU’RE WAKING UP OVER IN SLIDELL. YOU WOKE UP TO SOME VERY HEAVY RAIN AND NOW MOST OF THAT IS MOVING JUST TO THE SOUTH OF YOU. SO JUST TO THE SOUTH OF THE TWIN SPAN RIGHT NOW, BUT STILL SEEING SOME STEADY RAIN OVER YOU, THE LITTLE WOODS NEIGHBORHOOD STARTING TO SEE SOME HEAVY RAIN. SHOIGU. SO GENTILLY YOU’RE LOOKING AT MORE OF A STEADY RAIN STARTING TO MAKE ITS WAY ON THROUGH. THIS IS JUST ON THE OTHER SIDE. METAIRIE. AND THEN CONTINUING TO MAKE ITS WAY ON OVER. SO IF YOU’RE IN NEW ORLEANS EAST, YOU’RE PROBABLY GOING TO WAKE UP SEEING SOME RAIN HERE SHORTLY. IF YOU’RE ABOUT TO LEAVE. NOW ON THE OTHER SIDE OF THIS, WATCHING SOME VERY HEAVY RAIN OUT TOWARDS BATON ROUGE, BUT NOT HOLDING TOGETHER VERY WELL, YOU SEE HOW IT’S KIND OF LIGHTING UP AS IT’S HEADING OUT TOWARDS DONALDSONVILLE RIVER PARISHES. YOU’RE SEEING SOME STEADY RAIN RIGHT OVER THE CAUSEWAY, ALMOST SEEING SOME CLEARING, ALMOST ON THE TAIL END OF THIS. BUT UP 55 BONNET CARRE SPILLWAY STILL LOOKING AT SOME RAIN. AND I DO HAVE MORE ON THE NORTH SHORE FOR YOU. SO INDEPENDENCE, YOU’RE SEEING THAT RAIN, EVERYONE. PRETTY MUCH A TANGIPAHOA PARISH STARTING TO SEE THAT RAIN FILL IN FOR YOU. SO HEADING OFF TO WORK ANYTIME SOON. GRAB THE RAIN GEAR. YOU WILL NEED IT. YOU’LL NEED IT AT SOME POINT FOR THIS MORNING. DEFINITELY FOR THE AFTERNOON. WE MAY GET SOME BREAKS IN HERE BY THE MIDDLE OF THE MORNING INTO EARLY AFTERNOON HOURS, BUT I’M SAYING BY THE TIME WE GET TO THREE 4:00 MORE, THIS WILL START TO ARRIVE WITH SOME OF THAT DAYTIME HEATING. THESE WILL START TO FIRE UP AGAIN. SO WE’RE NOT QUITE DONE WITH OUR HEAVY RAIN FLOOD THREAT AT ALL. AS I MENTIONED, THIS IS GOING TO GO ON FOR PRETTY MUCH THE REST OF THE WEEK. LET’S TALK ABOUT WHAT’S GOING ON IN THE TROPICS. SO AS WE’RE WATCHING THE SYSTEM MAKE ITS WAY ON UP TO TEXAS, AND THEN AS IT DOES, IT’S GOING TO TRY TO REEMERGE OUT HERE OVER THE GULF AS IT DOES. IT’S GOING TO TRY TO DEVELOP INTO SOMETHING MAYBE CLOSE TO A TROPICAL DEPRESSION. BUT EITHER WAY IT GOES, IT’S GOING TO BRING SOME HEAVY RAIN TO THE AREA. SO HERE’S THURSDAY. EXPECTING THIS TO MOVE ON IN COULD BRING A LOT OF VERY HEAVY RAIN TO CENTRAL NORTHERN LOUISIANA FOR US. SO WE’RE DEFINITELY STILL LOOKING AT SOME VERY HEAVY RAIN CENTRAL MISSISSIPPI. THAT’S ALSO GOING TO BE THE CASE FOR YOU AS WELL. SO RAIN FOR PRETTY MUCH THE REST OF THE WEEK. BUT HERE’S THE FORECAST. RAINFALL TOTALS. YOU CAN SEE WHERE THE HOT SPOTS ARE GOING TO BE PRETTY MUCH JUST TO THE SOUTH OF NEW ORLEANS ON UP. SO LOOKING AT ABOUT 3 TO 6IN, WORST CASE SCENARIO, LOOKING AT ABOUT MAYBE TEN PLUS INCHES, DEPENDS ON WHERE ALL OF THIS SETS UP. SO DON’T LET YOUR GUARD DOWN AS WE’RE HEADING INTO THE REST OF THE WEEK. JUST KNOW THIS FORECAST IS PROBABLY GOING TO CHANGE AS WE’RE HEADING INTO THE NEXT 12 HOURS, 24 HOURS OR SO. PROBABLY GOING TO LOOK DIFFERENT WHEN I’M WITH YOU TOMORROW. BUT AS FAR AS THE REST OF THE RAIN, YOU’RE SEEING WHERE IT’S PRETTY MUCH GOING TO TRACK TEXAS. HOUSTON GOING TO SEE QUITE A BIT OF RAIN AS WELL. THAT’S GOING TO BE THE BIG STORIES AS WE HEAD INTO THE NEXT SEVERAL DAYS. SPEAKING OF THE NEXT SEVERAL DAYS, ALERT DAYS WILL CONTINUE FOR US IS THAT HEA
