7/22/2026, 8:26:31 AM
Core Event
Tropical Storm Bertha, the second named system of the 2026 Atlantic season, organized in the eastern Gulf of Mexico and moved northwestward toward the northern Gulf Coast. The National Hurricane Center (NHC) recorded maximum sustained winds of 60 mph and a central pressure of 995 mb on the afternoon of July 20, 2026. The storm tracked west at 6 mph, with forecasts calling for landfall in coastal Louisiana late Wednesday and weakening through Friday.
Background & Context
Bertha follows Tropical Storm Arthur, which struck the Gulf Coast in June 2026 and left parts of Mississippi still recovering from flooding. Early season activity has prompted heightened vigilance among coastal officials despite NOAA’s outlook for a below-average Atlantic hurricane season.
Timeline
- July 20, 2026 – Satellite imagery shows Bertha forming over the eastern Gulf of Mexico.
- July 21, 2026 – NHC deputy director Jamie Rhome said Bertha was likely at its peak intensity.
- July 22, 2026 (scheduled) – New Orleans NWS office warned that wind shear would increase overnight, likely weakening the storm.
- July 24, 2026 (scheduled) – Weather Service warned of minor to moderate coastal flooding from the Mississippi/Alabama border to the mouth of the Mississippi River.
Data & Statistics
- Wind: NHC reported 60 mph; an earlier NWS bulletin listed 40 mph.
- Movement: 6 mph northwestward (NHC) versus 3 mph west-northwest (CBS).
- Rainfall: Forecasts call for 2–4 in (5–10 cm) of rain from western Florida to southern Louisiana, with isolated amounts up to 8 in.
- Storm surge: 2–4 ft near the Mississippi River mouth; up to 4 ft along Louisiana’s central coast.
- Sea state: Waves up to 6 ft and heightened rip-current risk along beaches.
Official Statements & Responses
- Jamie Rhome (NHC deputy director) indicated Bertha had likely reached its peak intensity on July 21.
- The New Orleans NWS office projected increasing wind shear through July 22, expecting the storm to weaken.
- Michael Buchanan, meteorologist with the Louisiana NWS, identified wind as the primary hazard for the anticipated Louisiana landfall.
- Jeff Clark, spokesperson for Mississippi’s Harrison County, noted that six sand-bag distribution sites were opened in response to potential flooding.

Impact & Local Response
Coastal municipalities in Mississippi, Louisiana, and Florida opened sand-bag sites and posted red-flag warnings for dangerous surf and rip currents. Beaches from Pensacola to the Mississippi-Alabama border were largely closed to swimming, and local businesses reported a mix of reduced tourist activity and steady patronage from residents seeking shelter from the rain.
Conflicting Reports & Gaps
Sources differ on Bertha’s maximum sustained winds: the NHC and several outlets list 60 mph, while a CBS bulletin cites 40 mph. No additional meteorological data have been released to reconcile this discrepancy.
What’s Next
Hurricane-Hunter aircraft were scheduled for flights on July 21 and July 22 to obtain direct measurements. Forecasters expect the storm to continue weakening as it moves inland, with the greatest rainfall and surge threats remaining offshore. Residents are advised to monitor official updates and heed local flood-risk advisories.
