Hurricane Maria
Winds: 80 mph  Pressure: 963 mb  Motion: N 7 mph
 
Synopsis: 
Maria has slowed down as it moves northward several hundred miles east of the southeastern coast of the U.S. The storm has weakened to a category 1 hurricane. Forecast models continue to call for Maria to remain offshore the Mid Atlantic coast. However, the wind field is large enough that a Tropical Storm Warning has been issued for the easternmost portion of North Carolina. Sustained winds are expected to remain below 50 mph on land.

Track Forecast: Maria has slowed down as it responds to a high-pressure ridge located over the Northeast. A slow northward motion is expected to continue for the next 48 hours. Thereafter, an approaching low-pressure trough will cause the storm to turn toward the ENE and pick up speed as it heads out to sea. Forecast models are in excellent agreement, showing a track that remains offshore the coast of North Carolina as Maria makes it closest pass to the mainland U.S.

Intensity Forecast: Maria continues to weaken as its structure is inhibited by cool ocean water, moderate vertical wind shear, and a relatively dry atmosphere. This weakening will continue as the storm moves slowly northward over the next couple days.
