Tropical Storm Bertha’s Gulf-Coast Journey: Landfall, Forecasts, and Impacts
7/23/2026, 11:32:51 AM
Core Event
On July 22, 2026, Tropical Storm Bertha made landfall in St. Bernard Parish, Louisiana, just east of New Orleans, with maximum sustained winds reported between 45 mph and 60 mph. The storm’s center moved west-northwest at 6–12 mph, keeping the strongest winds and thunderstorms south of the circulation. Over the next 48 hours Bertha tracked along the northern Gulf Coast, extending a tropical-storm warning from the Alabama-Florida border to Sargent, Texas, before weakening to a remnant low and dissipating inland over Texas by July 23, 2026.
Background & Context
Bertha was the second named system of the 2026 Atlantic hurricane season, following Tropical Storm Arthur. Seasonal forecasts highlighted a strong El Niño that typically suppresses Atlantic activity, yet unusually warm Gulf waters raised concerns about storm intensity. Persistent northerly wind shear and dry mid-level air limited Bertha’s organization, producing a “lopsided” structure with most convection displaced offshore.
Data & Statistics
- Wind: Sustained winds 45 mph (most sources); some advisories listed 50 mph or 60 mph early in the cycle.
- Pressure: Minimum central pressure reported between 1000 mb and 1003 mb.
- Rainfall: Forecast 1–4 inches across the Gulf Coast, with isolated totals up to 6 inches.
- Storm-size: Tropical-storm-force winds extended 100–160 mi from the center, primarily south of the circulation.
- Storm surge: Expected 1–3 ft above normal along the Louisiana-Mississippi-Alabama coast; 2–4 ft in the Florida Panhandle.
- Forward speed: 6–12 mph, accelerating on July 23, 2026 as the system approached Texas.
Official Statements & Responses
Louisiana Governor Jeff Landry urged residents not to be complacent, noting “it doesn’t take a major hurricane to do major damage to communities in Louisiana.” State climatologist Jay Grymes described the event as an “in-and-out” scenario with “some pockets of flooding.” The National Hurricane Center scheduled intermediate updates for 1 a.m. CDT and a full advisory for 4 a.m. CDT on July 23, 2026.
Conflicting Reports & Gaps
- Wind speed: The New York Times and local outlets listed 45 mph at landfall, while AP’s Robbie Berg cited 50 mph, and AccuWeather’s Alex DaSilva referenced earlier 60 mph measurements.
- Pressure: Sources vary between 1000 mb (NHC advisory) and 1003 mb.
- Rainfall forecasts: Most agencies predict 1–4 inches, yet AccuWeather’s “Local StormMax™” model projected up to 15 inches, a figure not echoed elsewhere.

Bertha illustrated how moderate tropical storms can still pose multi-hazard threats—wind, surge, rain, and dangerous surf—while environmental factors such as wind shear and dry air can prevent rapid intensification, even amid anomalously warm Gulf waters.
