New Orleans flood watch: When will it rain? How much will I get?

A flood warning has been issued for New Orleans and all of southeast Louisiana

A flood warning is in effect from 6 a.m. Monday to 12 p.m. Tuesday

SCHEMATIC. Our weather is still mild this evening and temperatures will be too cold for the next few days. For this reason, we are at risk of thunderstorms that could bring heavy rain. WHERE WE STILL STAND IN THE 60S. 65 BOGALUSA TO 66 HERE IN TOWN, GRAND ISLE. It’s still 70 degrees on the Mississippi coast, with 66 degrees. These are typically high temperatures for this time of night. EVEN 1 OR 2 DEGREES ABOVE, FOR THIS TIME OF YEAR. WHAT DO WE SEE HERE? WE HAVE A STORM SYSTEM. THE FRONT. That comes through. THIS FRONT CALLS THROUGH A QUITE STRONG AREA OF AT LEAST COLDER AIR. That will eventually try to move in, but it will be two separate storm systems rolling across this front as it stalls across the region. CLASSIC SETUP TO GIVE US A CHANCE AT FLOOD RISK. While we’re looking at the rain, you can see how it matches up with these radar images. Let’s take a look at our WDSU First Warning Weather Doppler Radar and see what it looks like up there. And we’ll see that this radar reflects exactly what we had. And I put it into action. We have a few showers on the north shore. The rain has effectively started for you too. COVINGTON MANDEVILLE. MADISONVILLE. SLIDELL. You’re on the South Rim, so when you make your way out there won’t be much rain north of you. IT IS FROM PICAYUNE, BOGALUSA, PEARL RIVER POPLARVILLE. A LITTLE LIGHT RAIN, A LITTLE LIGHT RAIN TO THE RIVER. Parishes of Saint John the Baptist. AS YOU REACH SAINT JAMES RUDOLPH AKERS IT’S A LITTLE LIGHT RAIN AND WE’RE TRYING TO FIND SOME SHOWERS NOW THAT MAY SPREAD WEST OF HOUMA. So again, that’s pretty consistent with what I got in this short-term and high-resolution forecast. Let’s get straight to the point and walk you through it straight away when it really starts to rain for you. And the worst storms are starting to come. So we see that it’s not so bad tonight. BUT BREAKFAST TOMORROW we’ll start to see the potential for more severe storms. NORTH BANK IN ONE ROUND. When we arrive in southern Terrebonne in the morning, the temperatures are a few degrees cooler around where we are. So the thing is, you don’t really need to stay warm for the next few days, but you know how it is for us here. You know, it’s even blowing between 65 and 75 degrees out there. IT’S SOMETHING COOL FOR US BUT SEE TOMORROW’S FORECAST HERE. Stronger storms as we begin to rise in the warmest parts of the day. And that’s typical from 9 a.m. to about 4 p.m., and the stronger storm activity tends to be a little further south. My biggest concern with most of the heavier rains is really New Orleans. OFF TO THE COAST, GENERALLY SOUTH OF I-12. This is where most of the state comes into play. THEN there will be a lull as the rain tapers off until at least the hour of sunset on Monday evening. As for the temperature, I told you it won’t be too cold. And considering the time of year and the winter season, we are pretty mild. 72 WHERE WE RELEASE SOME FORECAST DATA FOR THE FIRST ROUND OF RAIN SAYS ONE TO A FEW INCHES OF RAIN IS POSSIBLE. AND THAT IS A FLOODING RISK IF WE ARE BELOW THAT LEVEL 2. The risk of possible flooding is low. And that’s why the flood watch runs from 6 a.m. until midday Tuesday. THEN the next round of rain will arrive as soon as we get to Tuesday morning. The warmest parts of the day, as you can see, the more severe storms are more on I-12 and more south just because of the timing of where they line up and the time of day. And then there is one last possible round of rain, I would like to show our high-resolution data. BUT THERE MAY NOT BE THAT MUCH RAIN. JUST ONE LAST GENERAL RAIN. IT’S 70. COULD STILL HAVE THIS ENERGY FOR THE THUNDERSTORMS AND LOOK AT THESE TWO-DAY FORECAST TOTALS. ABOUT THREE, FOUR AND FIVE INCHES. ANOTHER TYPE OF A WIDER VIEW, 1 TO 2 INCHES WIDER OVERALL, BUT SOME RANGES OF 3 TO 4 POSSIBLE. Therefore, local flooding is the biggest risk here. BUT I ALSO CAN’T SAY IF I GO INTO TUESDAY, 1 OR 2 STORMS THAT WILL BE STRONG WITH A GUST OF WIND, NO RISK OF TORNADOES OR HAIL. So it’s best to have the rain gear with you, especially for Monday to Tuesday. Rain is most likely and heaviest on the south bank. Now as we get past this front and into Wednesday, it’s windy and much, much colder. So prepare yourself for it. BUT WE HAVE A FEW DAYS. Did I mention it’s WDSU? FIRST WARNING: EVEN DAYS WITH THE INFLUENCE OF WEATHER. THESE ARE ALREADY ISSUE ON MONDAY AND TUESDAY. Get ready for the rain. We would be happy to advise you
