Overview

  • The National Hurricane Center lowered the system’s chance of developing into a cyclone to 30 percent over both the next 48 hours and the next seven days.
  • Satellite, surface, and radar observations indicate the broad area of low pressure remains disorganized with shower and thunderstorm activity displaced west of its center.
  • The National Weather Service issued a flood watch through Friday night for the New Orleans region with rainfall rates up to four inches per hour and totals reaching eight inches in some spots.
  • Heavy downpours and localized flash flooding are expected from the Florida Panhandle through Louisiana, Alabama, and Mississippi as the disturbance moves inland by week’s end.
  • If the system organizes into a tropical storm before landfall it would be named Tropical Storm Dexter, marking the fourth named storm of the 2025 season after Andrea, Barry, and Chantal.
