s summer in the Northern Hemisphere draws to a close, the Gulf of Mexico once again became a brewing ground for storms. This time, it was Hurricane Francine that captured the attention of meteorologists and coastal communities alike. After forming off the eastern coast of Mexico, Francine intensified rapidly over the Gulf’s warm waters, ultimately setting its sights on the Louisiana coastline, threatening to bring severe storm surges, heavy rainfall, and powerful winds.
Francine started as a tropical storm on September 9, 2024, in the eastern Gulf of Mexico. By September 10, as the storm moved over waters several degrees warmer than average, it quickly gained strength, reaching Category 1 hurricane status with sustained winds of 65 mph (105 km/h). This transition from tropical storm to hurricane was fueled by the Gulf’s warm sea surface temperatures (SSTs), which had been notably high throughout early September. According to NASA’s Multiscale Ultrahigh Resolution Sea Surface Temperature (MUR SST) project, the waters in the southwestern Gulf were a few degrees above the 82°F (27.8°C) threshold commonly recognized as ideal for hurricane intensification.
Data from the Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA-21 satellite captured a detailed view of Francine on the afternoon of September 10, showcasing the storm’s size and intensity. The VIIRS image, acquired at 2:25 p.m. Central Time, revealed the sprawling cloud cover and organized structure typical of a strengthening hurricane. The near-real-time tracking and imaging capabilities of NOAA and NASA satellites were crucial in providing meteorologists with the data needed to predict Francine’s path and potential impact.
As Francine neared landfall on September 11, emergency preparations were underway. The National Hurricane Center projected a significant storm surge of 5 to 10 feet (1.5 to 3 meters), particularly around Louisiana’s Vermilion Bay area. Additionally, forecasts anticipated sustained hurricane-force winds of 74 mph (119 km/h) or higher in Morgan City, Louisiana, with widespread rainfall totals of 4 to 8 inches (100 to 200 mm) across the Gulf Coast.
In light of the storm’s intensity, Louisiana officials issued mandatory evacuation orders for Cameron Parish and advised residents in other low-lying areas outside levee protection to leave. Preparations also included collaboration between local emergency management teams and national agencies like FEMA, with NASA’s Disasters Program activated to support relief efforts by providing satellite imagery and data products to monitor flooding, assess damage, and assist in response coordination.
NASA’s Disasters Program mobilized its resources to aid in hurricane preparedness and response. This activation meant that crucial satellite data, including maps of storm surge projections and rainfall predictions, became available to agencies managing evacuation routes, rescue efforts, and post-storm recovery plans. NASA’s mapping portal, a valuable tool for emergency response teams, provided open-access data to help local authorities and organizations monitor Francine’s progress and respond more effectively to the storm’s aftermath.
Hurricane Francine marks the third hurricane to make landfall in the United States this season, highlighting the persistent vulnerability of the Gulf Coast to intense tropical storms. Warmer sea surface temperatures, partly due to seasonal climate patterns and the region’s natural characteristics, create an environment ripe for hurricanes. The data gathered from this and previous storms will contribute to climate studies, helping scientists understand trends and improve future forecasts.
As Francine demonstrates, hurricanes are complex weather systems with far-reaching impacts. While advanced satellite monitoring has enhanced our ability to forecast and prepare for these events, coastal communities remain on the frontlines, adapting their response strategies in real-time as each storm approaches.
