We continue to monitor Ida as it approaches, expected to make landfall Sunday afternoon/evening. A hurricane Warning is in effect for areas of southern/central LA. A Tropical Storm Warning is in effect for parts of coastal/southern MS and western LA. #LAwx #MSwx
We want to continue to stress that this WILL be a DANGEROUS and LIFE-THREATENING storm. There WILL be significant wind damage. Prepare for widespread power outages and tree/structural damage in these purple/red areas on the graphic below.
Hurricane Ida is expected to deliver LIFE-THREATENING Flash Flooding for portions of Louisiana and coastal MS. 8-16 inches of rainfall is possible and a Flash Flood Watch is in effect due to this.
DEVASTATING storm surge is expected in purple highlighted areas in the graphic below. EXTENSIVE storm surge in red/orange areas. A Storm Surge Warning is in effect for southern LA and coastal MS. A Storm Surge Watch is in effect for parts of the AL border and western LA coast.
We also have the potential to see isolated tornadoes across southern/eastern Louisiana and coastal Mississippi.
Please finish up all preparations by SUNSET this evening. Tropical storm force winds could arrive as early as overnight. If you are leaving you need to do so TODAY. If you wait until Sunday morning it will be too late.

The numbers are in & this summer was H-O-T.

ALL our automated sites tied/broke their warmest summer records (Jun-Aug), some by astounding margins.

We don't have enough space to go over every record that was set, but this thread will break down the more impressive ones.

(1/9) Text next to clipart of a record on fire with the NWS logo in the middle of the record. The text reads as follows. Record Breaking Summer of 2023. Every one of our automated stations broke or tied their records for warmest summer (June-August)! This includes climate sites at Baton Rouge and Gulfport, with records back to the 1890s! New Orleans (MSY), Gulfport, Slidell and Pascagoula all broke their all-time highest temperatures, and New Orleans Lakefront tied its all-time highest temperature! Numerous monthly and daily records were also broken!
Baton Rouge broke its warmest summer on record by an almost unfathomable 2.8 degrees! Records go back to 1892.

The all-time high temperature wasn't reached, but there were an astounding 30 days with a high at or above 100 degrees! (Avg back to 1892 is only 1/year)

An astounding 27 days with a low temperature of 80° or warmer! The previous record was only 4, set in 2019. 21 of the warmest 25 days on record occurred this summer!
New Orleans (MSY) beat the record for warmest summer by an impressive 1.2 degrees with records back to 1946.

On August 27th, a new all-time warmest temperature was also set at the site when it reached 105 degrees compared to a previous all-time high of 102.

🌀 As we gear up for the potential impacts from TD9 which could be #Ida later today or tonight there are a few thing we would like everyone to understand and be prepared for. #LAwx #MSwx Image
💆 DO NOT PANIC! Be prepared, stay up to date, and try to remain calm. You have time IF you begin today. If the track continues as forecast, conditions will likely begin to go downhill late Saturday. This gives you today, Friday, & even early Saturday. #LAwx #MSwx Image

🌀10PM CDT Update on Tropical Storm #Zeta. Starting to see some steady strengthening trend now with max winds at 70mph. Impacts across parts of SE LA and southern MS remain likely on Wednesday.

Lets break down each specific threat one at a time...(1/6)
1. 💨 Wind: Strong winds will be the primary threat when #Zeta makes landfall. These winds may lead to isolated to scattered power outages, some tree damage and even some damage to some structures - especially near the center of the track. (2/6) #lawx #mswx
2. 🌊 Storm Surge: Moderate/major coastal flooding is possible in the Storm Surge Warning areas. Highest water levels are expected during the high tide cycle Wednesday, lasting into the overnight hours before water levels come back down Thursday. (3/6) #lawx #mswx #Zeta
