Initial damage assessments are underway in areas affected by Ida, which made landfall yesterday in southeastern Louisiana as a Category 4 hurricane. Ida brought heavy rains, high winds, and storm surge that have caused catastrophic conditions, including significant flooding. Some of the initial reports indicate:

Multiple water systems have implemented boil water advisories, including Terrebonne Parish (where Houma is located) and Jefferson, St. Tammany, and St. Charles Parishes, which are in the New Orleans area.
- The Louisiana Safe Drinking Water Program has started reporting Ida-related boil water advisories and water outages here. As of 11:00 AM ET, it reported 14 systems were under boil water advisories and 18 systems were experiencing water outages.
The Sewer & Water Board of New Orleans (SWBNO) lost all external power but is using self-generated power sources and backup generators to drain stormwater and pump drinking water into the city. The power loss impacted its sewer pumping stations; there was no backup power to operate any of those that were impacted. SWBNO reports it has worked to obtain backup power for some of these stations and will mobilize those units when it is safe to traverse the city. To prevent sewage backups, it asked residents to limit water usage.
Over 1 million customers in Louisiana were without power as of this morning, according to PowerOutage.US. These numbers include customers in New Orleans, where the entire city was reportedly without power.
- Approximately 130,000 customers were without power in Mississippi, where Ida is currently located and is expected to pass over today and tomorrow.
- According to energy sector representatives on the CISA and FEMA conference call yesterday, power restoration for some affected areas may take up to three weeks.

WaterISAC will continue to report on impacts in upcoming advisories.

As of 11:00 am ET, Ida was located over western Mississippi and moving northward at 9 mph. It is expected to start traveling a northeastern direction at a slighter higher velocity, moving across the Tennessee Valley tomorrow and the Ohio Valley, Central/Southern Appalachians, Mid-Atlantic, and parts of the Northeast over the rest of the week. Ida was a tropical storm, with maximum sustained winds near 40 mph. Additional rapid weakening is forecast during the next day or so, and Ida is expected to become a tropical depression this afternoon.

Through this morning, the National Hurricane Center (NHC) predicts Ida will produce additional rainfall totals of 2 to 4 inches with localized higher amounts possible across portions of southeast Louisiana into far southern Mississippi. Storm total rainfall accumulations of 10 to 18 inches with isolated maximum amounts of 24 inches are expected. This rainfall has already contributed to life threatening flash flooding and significant riverine flooding along Louisiana's southeast coast, which are expected to continue farther inland. As Ida starts traveling northeast, significant flash flooding is possible from the Lower Mississippi Valley through the Middle Tennessee Valley, Ohio Valley, Central/Southern Appalachians, and into the Mid-Atlantic. Rainfall may generate widespread minor to isolated major riverine flooding from the Lower Mississippi Valley into far western Alabama. Additionally, the following areas are under tornado watch until later tonight: southeast Mississippi, southern Alabama, and the western Florida Panhandle.
