Parish-by-parish impacts from Isaias in southeast Louisiana, tell me about this news today

Tropical Storm Isaias has formed in the Gulf of Mexico, prompting tropical storm watches and warnings for parts of the northern Gulf Coast, including sections of southeast Louisiana. Because the current forecast track has shifted slightly eastward, the direct and severe impacts for southeast Louisiana are generally expected to be minor to moderate, though multi-hazard threats remain.

Here is the breakdown of expected impacts across southeast Louisiana:

• Plaquemines and St. Bernard Parishes (Eastern Coastal Zones): These areas are under a tropical storm watch (extending from the Jefferson-Plaquemines Parish line eastward). They face the highest risk in the region for coastal flooding and storm surge, with 1 to 3 feet of inundation possible along immediate coastal areas, which could cause low-lying and coastal roads to briefly flood or become impassable.

• Orleans and Jefferson Parishes: Expect gusty winds and periodic heavy downpours. Flash flood watches have been issued for parts of southeast Louisiana, meaning urban areas and locations with poor drainage could see ponding of water on roads. Local authorities have coordinated responses such as opening sandbag sites and permitting neutral ground parking.

• Western and Inland Parishes (West of I-55): These areas are on the drier western side of the system, meaning rainfall totals will drop off sharply. Locations further west may experience minimal rainfall (less than half an inch) and lower overall impacts as the storm’s core tracks further east toward Mississippi and the Florida Panhandle.

• General Wind Impacts: Sustained winds across the southeast parishes are generally expected to range between 20 to 30 mph, with occasional higher gusts reaching up to 40 mph, especially closer to the storm bands.
