Hurricane Maria Generates Swells Along East Coast; Tropical Storm Conditions in the Outer Banks Early Wednesday

Hurricane Maria hangs on Monday evening. The once major hurricane loses its symmetry and deep convection near its core. Maria combats stronger upper levels winds and taps into some cooler waters from upwelling from Jose. As of 5 PM it is a category 1 hurricane with 80 mph. It moves north at 7 mph. At this pace Maria will make its closest pass to the Outer Banks of North Carolina as a strong tropical storm early Wednesday. A strong upper level trough while guide Maria out to sea late in the work week. A Tropical Storm Warning is in effect for North of Duck to the North Carolina/Virginia border and North of Surf City to south of Cape Lookout. A Storm Surge Watch is in effect for Cape Lookout to Duck North Carolina. A mandatory evacuation was ordered from Ocracoke Island and Hatteras Island Monday afternoon.

While the center of Maria will pass well east of North Carolina, the tropical storm force wind field is quite large. Tropical storm force winds extend out 200 miles from its center. Sustained winds will approach low-end tropical storm force in the Outer Banks late Tuesday and early Wednesday. Below is the GFS wind speed forecast for early Wednesday morning. Higher gusts are likely. Outer bands will bring 1-2 inches of rain to the region, but this won’t be a big rainmaker.

Wave heights continue to build as Maria lifts northward in the western Atlantic. Dangerous swells reach the Mid Atlantic and even the Northeast Monday evening. Rough surf will continue through at least mid-week. This enhances the risk for rip currents and beach erosion. A 2-4 foot storm surge is possible from Cape Lookout to Duck North Carolina, including the sound side of the Outer Banks. Coastal flooding is possible starting Tuesday.

Elsewhere tiny hurricane Lee churns across the north central Atlantic. It weakens some at 5 PM. It is no threat to any land and will stay over the open Atlantic.

As October approaches, all eyes are on the western Caribbean and Gulf of Mexico. Long range models hint that pressure may lower in the western Caribbean during the first week of October. This is in line with climatology this time of year. Water temperatures are in the mid 80s. Our focus shifts to this region and away from the Main Development Region in the central Atlantic in the coming weeks.
