According to the NWS, Tropical Storm Bertha is expected to move near or along the southeast Louisiana coast between late Tuesday, July 21 and Wednesday, July 22. Tropical storm conditions, including sustained winds or frequent gusts between 39 and 57 mph, are possible across Metropolitan New Orleans beginning as early as late Tuesday night, with the greatest potential for impacts occurring Wednesday.
In addition to gusty winds, Bertha is expected to bring up to 2 to 4 inches of rainfall, with isolated totals up to 6 inches through Thursday. Heavy rainfall may result in localized street flooding, particularly in low-lying and poorly drained areas.
Sewerage & Water Board of New Orleans (SWBNO)
The Sewerage and Water Board of New Orleans (SWBNO) is actively preparing for Tropical Storm Bertha. A proactive approach is being taken by lowering canal levels, increasing staffing, and coordinating with partner agencies.
Current Drainage & Power Status
-
87 of 93 drainage pumps are available
-
93 MW of 25-Hz power available
-
Power Complex (SFC1–3, Turbine 6, Turbine 7 all 5 EMDS) are fully operational
Following lessons learned during Tropical Storm Arthur, the SFC settings have been adjusted to better accommodate significant voltage sags. These changes are intended to improve the ability of the static frequency changers to remain online during significant voltage fluctuations. Individual pumps may still be impacted by a combination of factors in the electrical distribution system, including voltage fluctuations or issues with the underground feeders.
There is sufficient power to operate older pumps to be able to pump out an inch of rain in the first hour and a half-an-inch of rain every hour thereafter. Any intense rainfall exceeding that capacity may cause street flooding.
The following equipment are out of service:
-
Frequency Changers #4 (Station D)
-
Frequency Changers #3 (Algiers)
-
Carrollton Plant Frequency Changer (electrical issue)
-
Turbine 4 (permanently removed)
At the Old Carrollton Underpass, three pumps are out of service. A temporary pump is deployed and is operational. All other underpass pumps are in service.
Residents are advised to remove debris from nearby catch basins. Leaves, litter and debris can prevent stormwater from draining properly and increase localized street flooding.
The SWBNO Emergency Hotline remains staffed and available 24/7. Customers can report leaks and other water or sewer-related emergencies by calling 52-WATER.
Entergy New Orleans is closely monitoring the tropical system in the Gulf and is preparing for severe weather that could impact our service territory.
Entergy encourages customers to take the time now to get personal storm plans in place and assemble emergency supplies, including any medical needs that require electricity.

New Orleans Regional Transit Authority (RTA)
Heavy rain, flooding, and other weather conditions associated with Tropical Storm Bertha could cause delays or service interruptions as the storm strengthens. Riders are encouraged to monitor RTA's website, Le Pass app, and social media (X, formerly Twitter) for the latest service updates.
RTA's Emergency Management team will continue monitoring conditions and provide updates as necessary.
The Office of Health and Human Services (OHHS), in coordination with City partners, will open the Rosenwald Recreation Center as a shelter for unhoused individuals ahead of Tropical Storm Bertha. For individuals needing transportation assistance to a shelter, please call 3‑1‑1 or 504‑539‑3266.
Opening: Tuesday, July 21, 2026 at 7 p.m.
Location: Rosenwald Recreation Center,1120 S. Broad Ave.
Individuals in need of shelter are encouraged to seek services before weather conditions deteriorate. For individuals needing transportation assistance to a shelter, please call 3‑1‑1 or 504‑539‑3266.
The OHHS team will continue its scheduled water distribution operation Tuesday from 8:30 a.m. to 11:30 a.m.
The public is urged to complete preparations before weather conditions begin to deteriorate Tuesday night:
-
Secure loose outdoor items. Bring inside or tie down patio furniture, grills, trash cans, decorations and other lightweight objects that could become airborne in strong wind gusts.
-
Clean your catch basins. Water needs somewhere to go. If the catch basin on your block is blocked by leaves, mud, litter or carnival beads, clear it where it is safe to do so. Cleaning your nearest catch basin is one of the most effective steps you can take to help reduce localized street flooding.
-
Charge essential devices. Charge cell phones, medical devices and backup battery packs in preparation for the possibility of isolated power outages.
