Tropical Weather Statement
Issued: 12:21 AM Jul. 21, 2026 – National Weather Service
This product covers Southeast Louisiana and South Mississippi NOAA HURRICANE HUNTERS FIND THAT THE DEPRESSION HAS STRENGTHENED INTO TROPICAL STORM BERTHA NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - None * CURRENT WATCHES AND WARNINGS: - A Storm Surge Watch and Tropical Storm Watch are in effect for Eastern Orleans, Lower Plaquemines, Lower St. Bernard, Southeast St. Tammany, Southern Hancock, Southern Harrison, and Southern Jackson * STORM INFORMATION: - About 270 miles east-southeast of New Orleans LA or about 220 miles east-southeast of Gulfport MS - 28.6N 86.0W - Storm Intensity 40 mph - Movement West-northwest or 300 degrees at 3 mph SITUATION OVERVIEW ------------------ Tropical Storm Bertha is currently south off the coast of the Florida Peninsula and will gradually continue to move northwest. Some slight additional strengthening is possible before reaching the region sometime midweek. Bertha is forecast to bring the threat of tropical storm force wind gusts, locally heavy rainfall south of I-10, and storm surge. The coastal areas of Mississippi and southeast Louisiana will have the greatest threat, especially south of I-10. Tropical storm watches remain in effect for the Mississippi coast and southeast Louisiana east of the mouth of the Mississippi River. A tropical storm watch also remains in effect for the coastal waters, sounds east of the mouth of the Mississippi as well as for Lake Borgne. POTENTIAL IMPACTS ----------------- * WIND: Prepare for hazardous wind having possible limited impacts across the Louisiana and Mississippi coasts. Potential impacts in this area include: - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Many large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Some fences and roadway signs blown over. - A few roads impassable from debris, particularly within urban or heavily wooded places. Hazardous driving conditions on bridges and other elevated roadways. - Scattered power and communications outages. Elsewhere across Southeast Louisiana and South Mississippi, little to no impact is anticipated. * SURGE: Prepare for life-threatening surge having possible significant impacts across the Louisiana coast east of the mouth of the Mississippi River and coastal Mississippi. Potential impacts in this area include: - Areas of inundation with storm surge flooding accentuated by waves. Damage to several buildings, mainly near the coast. - Sections of near-shore escape routes and secondary roads become weakened or washed out, especially in usually vulnerable low spots. - Major beach erosion with heavy surf breaching dunes. Strong and numerous rip currents. - Moderate damage to marinas, docks, boardwalks, and piers. Several small craft broken away from moorings, especially in unprotected anchorages. Elsewhere across Southeast Louisiana and South Mississippi, little to no impact is anticipated. * FLOODING RAIN: Prepare for dangerous rainfall flooding having possible significant impacts south of I-10, especially near the southeast Louisiana coast. Potential impacts include: - Moderate rainfall flooding may prompt several evacuations and rescues. - Rivers and tributaries may quickly become swollen with swifter currents and overspill their banks in a few places, especially in usually vulnerable spots. Small streams, creeks, canals, and ditches overflow. - Flood waters can enter some structures or weaken foundations. Several places may experience expanded areas of rapid inundation at underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water as storm drains and retention ponds overflow. Driving conditions become hazardous. Some road and bridge closures. Prepare for locally hazardous rainfall flooding having possible limited impacts across coastal Mississippi and elsewhere in southeast Louisiana along the I-10/I-12 corridor. * TORNADOES: Little to no tornado impacts are anticipated at this time across Southeast Louisiana and South Mississippi. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * OTHER PREPAREDNESS INFORMATION: When securing your property, outside preparations should be concluded as soon as possible before conditions deteriorate. The onset of strong gusty winds or flooding can cause certain preparedness activities to become unsafe. Check on those who may not be fully aware of the situation or who are unable to make personal preparations. If you are a visitor, know the name of the county or parish in which you are located and where it is relative to current watches and warnings. If staying at a hotel, ask the management staff about their onsite disaster plan. Listen for evacuation orders, especially pertaining to area visitors. Closely monitor weather.gov, NOAA Weather Radio and local news outlets for official storm information. Listen for possible changes to the forecast. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information on creating an emergency plan see getagameplan.org - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in New Orleans LA around 10pm, or sooner if conditions warrant.
