As Tropical Storm Bertha tracks westward across southern Louisiana, it is already bringing disruptive tropical storm-force wind gusts and hazardous conditions for coastal beachgoers, but a far more dangerous consequence of the storm is unfolding hundreds of miles to the east, where its abundant tropical moisture is set to drive extreme flood rainfall across parts of the U.S. Southeast and East Coast through the end of the week.

According to official updates from the U.S. National Hurricane Center, Bertha made its official landfall at 3 p.m. Eastern Time in St. Bernard Parish, located in Louisiana’s southeastern region. Remarkably, the storm’s most intense wind gusts and heaviest downpours have remained offshore, with the system recording maximum sustained winds of 45 miles per hour at the moment its center moved onshore.

Unlike many tropical systems that pose their greatest threat near their landfall zone, Bertha’s most impactful hazard is developing far from its Louisiana landing point. The storm’s trapped tropical moisture is interacting with a slow-moving cold front stretching across the U.S. East Coast, creating conditions primed for extreme heavy rainfall and widespread flooding through Thursday. The affected areas include southeast Virginia, multiple regions of the Carolinas, and northern Georgia.

Meteorologists from CNN Weather explain that a stationary cold front is drawing Bertha’s moisture northward and eastward from the Gulf of Mexico coast into the Southeast, creating a continuous feed of water vapor that sustains the heavy rain systems. As for Bertha itself, forecasters predict the storm will gradually lose strength as it pushes westward toward coastal Texas, with its center expected to reach the region by Thursday evening. Even as it weakens, the remnant system will bring scattered rain and occasional gusty winds to coastal Texas, while continuing to feed tropical moisture into the flood-bearing storm systems lingering over the Southeast.

Antigua and Barbuda’s environment ministry has confirmed a key leadership transition within its environmental governance structure, naming long-standing climate action leader Ruleta Camacho-Thomas as Acting Director of the country’s Department of Environment. The change officially takes effect on July 20, and comes as outgoing director Ambassador Diann Black Layne steps into pre-retirement leave ahead of her full departure from the role.

Beyond her new acting appointment, Camacho-Thomas already holds the position of Antigua and Barbuda’s National Climate Ambassador, bringing decades of frontline experience in environmental advocacy to the top leadership post. Over the course of her professional career, she has been a consistent and vocal representative for the twin-island nation at major regional and global environmental forums, where she has centered the needs and concerns of small island developing states (SIDS) in worldwide climate policy negotiations.

A leading voice for global climate justice, Camacho-Thomas has worked for years to amplify awareness of the unequal burden of climate change carried by low-lying and vulnerable island nations. She has repeatedly drawn international attention to the existential threats these countries face from accelerating sea-level rise, growing intensity of extreme weather events, and a cascade of other climate-driven hazards that disproportionately impact SIDS despite their minimal contribution to global greenhouse gas emissions.

In her new capacity as Acting Director, Camacho-Thomas will take on oversight of all existing programs run by the Department of Environment. She will also maintain her ongoing work advancing Antigua and Barbuda’s core environmental and climate action priorities, working to deliver progress both at the domestic policy level and on the international climate advocacy stage.

The U.S. National Hurricane Center has expanded tropical storm watches westward to cover the far southwestern coastline of Louisiana and the upper Texas coast, as Tropical Storm Bertha churns slowly across the northern Gulf of Mexico. As of 7:00 AM Central Daylight Time (12:00 UTC), the storm’s center was located approximately 45 miles (75 kilometers) northeast of the mouth of the Mississippi River, advancing westward at a steady 5 miles per hour (7 kilometers per hour). Meteorologists project this general westward track will hold through Friday, with only a slight increase in forward speed expected, bringing Bertha close to or directly along the northern Gulf Coast over the next 48 hours.

Data collected by a NOAA Hurricane Hunter research aircraft confirms the storm maintains maximum sustained winds of 50 miles per hour (85 kilometers per hour), with stronger gusts recorded near the storm’s core. While current wind intensity holds steady, forecasters predict gradual weakening over the coming days as the system interacts with land and cooler northern Gulf waters. Tropical storm-force winds currently extend 105 miles (165 kilometers) outward from Bertha’s center, with a recent gust of 49 mph (79 km/h) recorded at Florida’s Pensacola Naval Air Station.

Officials have outlined multiple hazards facing coastal communities across the region through the end of the work week. For wind impacts, tropical storm conditions are already spreading across portions of the northern Gulf Coast included in existing warning areas on Wednesday. Conditions could meet tropical storm thresholds in the extended watch area of southwestern Louisiana by Wednesday night, and across the upper Texas coast by Thursday or Thursday evening.

Storm surge remains a major flooding risk, with the combination of storm-driven water and high tides projected to push rising waters into normally dry coastal areas. If peak surge lines up with high tide, water levels could reach 2 to 4 feet above ground between the mouth of the Mississippi River and the Mississippi-Alabama border. Regions including the coast from Port Bolivar, Texas to the mouth of the Mississippi, the Mississippi-Alabama border to Florida’s Okaloosa/Walton County line, and Lake Pontchartrain all face a projected 1 to 3 feet of storm surge. Surge heights and flooding extent depend heavily on the timing of the storm relative to the tidal cycle, and can change dramatically over short coastal distances; local National Weather Service offices have issued site-specific guidance for at-risk communities.

Rainfall presents an additional hazard for inland and urban areas. Through Thursday, Bertha is expected to drop 1 to 4 inches of total rain across the central and western Gulf Coast, ranging from western Florida to southern Texas, with isolated pockets seeing up to 6 inches of accumulation. These intense rain bursts could trigger flash flooding, particularly in densely developed urban areas where drainage systems are easily overwhelmed.

Finally, swells generated by Bertha will continue pushing west along the northern Gulf Coast over the next several days, creating life-threatening surf and rip current conditions for beachgoers. Local weather offices urge residents and visitors to check local forecasts before heading to coastal areas. The National Hurricane Center will issue its next full public advisory on Bertha at 10:00 AM CDT (11:00 AM EDT), and Spanish-language updates are available via the agency’s official website. The deepest, most dangerous surge impacts will remain concentrated along the immediate shoreline, and residents in low-lying coastal zones should follow evacuation orders promptly if issued by local officials.

Against a backdrop of growing regional focus on environmental protection and sustainable waste management across the Caribbean, two senior technical officials from Antigua and Barbuda have completed a four-day specialized training workshop focused on advancing regulatory and practical capacity for handling hazardous chemicals and waste. Held in Trinidad and Tobago from July 7 to 10, the event, formally named the Joint Regional Training Workshop on Chemicals and Waste Multilateral Environmental Agreements, brought together environmental practitioners from across the Caribbean region to address shared challenges in environmental stewardship.

The Antigua and Barbuda delegation comprised J’herdine Browne, a graduate assistant attached to the country’s Department of Analytical Services, and Chris Winter, who serves as Landfill Manager at the National Solid Waste Management Authority. Over the course of the training program, participants delved into a diverse curriculum designed to build both foundational and advanced skills. Core topics covered included evidence-based hazardous chemicals and waste management protocols, the legal and operational requirements of international multilateral environmental agreements, frameworks for deepening cross-border regional cooperation, and practical application of the Globally Harmonized System of Classification and Labeling of Chemicals, a global standard designed to improve worker and environmental safety.

Beyond technical environmental content, the workshop also equipped attendees with transferable professional skills: participants received hands-on instruction in effective workplace mentoring strategies, the utilization of modern digital learning tools to expand ongoing education, and structured methods for sharing complex technical information across stakeholder groups. In a post-workshop statement, Antigua and Barbuda’s Department of Analytical Services outlined the long-term value of the participation for the small island nation. The department emphasized that the new skills and connections gained will directly contribute to strengthening local technical expertise, improving national-level implementation of binding international environmental agreements, and fostering closer collaborative ties between Caribbean nations working to address shared environmental challenges.
