Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Thu Jun 18 2026

For the North Atlantic...Caribbean Sea and the Gulf of America:

Offshore East Coast of the United States (Remnants of Arthur):
Showers and thunderstorms associated with a trough of low pressure
(the remnants of Arthur) are located over the southeastern United
States.  Environmental conditions appear marginally conducive for
some subtropical or tropical development on Friday or Saturday,
as the system moves northeastward at around 15 mph, and emerges
offshore the east coast of the United States and into the Western
Atlantic Ocean.

Regardless of development, heavy rainfall with the potential for
widespread and life-threatening flash flooding is likely across
portions of the Southeast United States during the next day
or two. Additional information on the rainfall potential can be
found in rainfall forecasts and Excessive Rainfall Outlooks from
the Weather Prediction Center online at wpc.ncep.noaa.gov.
More information on this system, including Gale Warnings, is
available in High Seas Forecasts issued by the National Weather
Service under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and
online at ocean.weather.gov/shtml/NFDHSFAT1.php

Formation chance through 48 hours...low...10 percent.
Formation chance through 7 days...low...10 percent.
