SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Okaloosa/Walton County Line in Florida to Morgan City, Louisiana * Metropolitan New Orleans and Lake Pontchartrain A Tropical Storm Watch is in effect for... * West of Morgan City, Louisiana, to Sargent, Texas * Lake Maurepas A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within 24 to 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within the next 12 to 36 hours. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 1000 AM CDT (1500 UTC), the center of Tropical Storm Bertha was located near latitude 29.8 North, longitude 88.6 West. Bertha is moving toward the west-northwest near 6 mph (9 km/h). A westward motion with an increase in forward speed is expected to resume later today and continue through Friday. On the forecast track, the center of Bertha will move near or along the Louisiana and upper Texas coasts through Thursday, and then move farther inland into Texas on Friday. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Weakening is forecast during the next couple of days, but Bertha could maintain tropical storm intensity through late Thursday. Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center. The estimated minimum central pressure is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Storm Bertha can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC. WIND: Tropical storm conditions will continue spreading across portions of the northern Gulf Coast within the warning area today. Tropical storm conditions are possible within the watch area in Louisiana by tonight and along the upper Texas coast by Thursday or Thursday night. STORM SURGE: The combination of storm surge and the tide will cause normally dry areas near the immediate coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Mouth of the Mississippi River, LA to MS/AL Border...2-4 ft Port Bolivar, TX to Mouth of the Mississippi River, LA...1-3 ft MS/AL Border to Okaloosa/Walton County Line, FL...1-3 ft Lake Pontchartrain...1-3 ft The deepest water will occur along the immediate coast. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. For a complete depiction of areas at risk of storm surge inundation, please see the National Weather Service Peak Storm Surge Graphic, available at hurricanes.gov/graphics_at2.shtml?peakSurge. RAINFALL: Bertha is expected to produce total rainfall amounts of 1 to 4 inches with isolated higher totals of 6 inches through Friday along the central to western Gulf Coast from Northwest Florida to southern Texas. This rainfall may produce isolated flash flooding, especially in urban areas. For a complete depiction of forecast rainfall associated with Bertha, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_at2.shtml?rainqpf and the Flash Flood Risk graphic at hurricanes.gov/graphics_at2.shtml?ero. SURF: Swells generated by Bertha will continue spreading westward along the northern Gulf Coast during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. A depiction of rip current risk for the United States can be found at: hurricanes.gov/graphics_at2.shtml?ripCurrents NEXT ADVISORY ------------- Next intermediate advisory at 100 PM CDT. Next complete advisory at 400 PM CDT. $$ Forecaster Berg]]>

Tropical Storm Bertha Forecast Discussion Number 13
Issued at 1000 AM CDT Wed Jul 22 2026 000 WTNT42 KNHC 221452 TCDAT2 Tropical Storm Bertha Discussion Number 13 NWS National Hurricane Center Miami FL AL022026 1000 AM CDT Wed Jul 22 2026 Bertha's satellite presentation has continued to degrade this morning, with all of the associated deep convection having been pushed well to the southwest of the exposed surface center due to strong deep-layer shear. That said, dropsonde data from NOAA and Air Force Reserve Hurricane Hunter aircraft indicate that the central pressure has changed very little from the previous advisory. The NOAA aircraft measured a peak 750-mb flight-level wind of 55 kt several hours ago, which equates to an initial intensity of 45 kt. More recent aircraft data suggest those winds may have decreased, but for now we'll continue to hold 45 kt in anticipation of additional aircraft and scatterometer data over the next few hours. Bertha's center has been deviating a bit north of the forecast track, and the current motion estimate is now 290/5 kt. Track model guidance insists that Bertha should resume a westward motion today, but wobbles and deviations like the current one are normal behavior for such a highly sheared tropical cyclone. Once a westward motion resumes, Bertha's center is likely to straddle the coast of Louisiana through Thursday and then reach the upper Texas coast by Thursday evening or night. The NHC track forecast lies along the northern edge of the guidance suite, partially to account for the recent northward jog and partially to closely follow the typically reliable HCCA and GDMI guidance. The expected weakening appears to be on the verge of starting, and the main question for the forecast is how quickly will Bertha lose intensity. Part of that equation is how much time the center will spend over land, while the system also continues to contend with strong northeasterly shear. The NHC intensity forecast maintains Bertha as a minimal tropical storm through 36 hours (around the time of a potential Texas landfall), but it's also possible that the cyclone could weaken to a depression or remnant low by that time. Like the track forecast, the intensity forecast is largely a blend of the latest HCCA and GDMI guidance. A remnant low forecast point is shown over Texas at 48 hours for continuity's sake, but Bertha could have dissipated by that time. Key Messages: 1. Tropical storm conditions are expected to continue along portions of the northern Gulf Coast from the western Florida Panhandle to southeastern Louisiana, including the Metro New Orleans area, through tonight. Tropical storm conditions are possible for portions of the southwestern coast of Louisiana and upper Texas coast tonight through late Thursday. 2. A Coastal Flood Warning is in effect for the Mississippi and Louisiana coastlines, where moderate coastal flooding is expected. 3. Isolated areas of flash flooding remain possible through Friday morning along the central to western Gulf Coast from Northwest Florida to southern Texas.
