NHC Monitors Southeast Low-Pressure System With 10 Percent Chance of Tropical Development

Rainfall along the Southeast shore will elevate coastal flooding risks this week without the system becoming a tropical storm.

Overview

  • Forecasters assign the offshore low-pressure area a 10 percent chance of tropical or subtropical development over the next seven days, with coastal waters still below the 80°F threshold needed for sustained intensification.
  • The disturbance is expected to move north-northeast at 10–15 mph, passing east of North Carolina by late Friday or Saturday before heading back out over the Atlantic.
  • Even without acquiring tropical characteristics, the system is set to produce heavy rainfall, local flooding and heightened rip currents along the Southeast coast this week.
  • Meteorologists caution against relying on single-model forecasts circulating on social media, which have been debunked as depicting a phantom early-season storm.
  • NOAA anticipates between 13 and 19 named storms this season, and the first will be designated Andrea.
