Hurricane Isaias brought wind and rain to the MidAtlantic states of the U.S. on Tuesday. Isaias weakened to a tropical storm on Tuesday morning as it moved over eastern Virginia. At 8:00 a.m. EDT on Tuesday the center of Tropical Storm Isaias was located at latitude 37.7°N and longitude 76.8°W which put it about 15 miles (25 km) south-southeast of Tappahannock, Virginia. Isaias was moving toward the north-northeast at 33 m.p.h. (54 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 993 mb.
A Tropical Storm Warning was in effect for the portion of the coast from Surf City, North Carolina to Eastport, Maine including Albemarle Sound, Pamlico, Sound, Long Island, Long Island Sound, Block Island, Martha’s Vineyard and Nantucket.
The center of Hurricane Isaias officially made landfall on the coast at Ocean Isle Beach, North Carolina. The maximum sustained wind speed at the time of landfall was 85 m.p.h. (135 km/h). A weather station at Oak Island, North Carolina measured a sustained wind speed of 76 m.p.h. and a wind gust to 87 m.p.h. (140 km/h).
The center of Isaias moved rapidly toward the north-northeast during the overnight hours and it passed between Richmond and Norfolk, Virginia. The strongest winds were occurring along the coast and over the Atlantic Ocean on Tuesday morning. A weather station at Duck, North Carolina measured a sustained wind speed of 48 m.p.h. (78 km/h) and a wind gust of 63 m.p.h. (102 km/h). A weather station at Poquoson, Virginia measured a sustained wind speed of 39 m.p.h. (63 km/h) and a wind gust to 56 m.p.h. (91 km/h). A weather station on Third Island which is near the Mouth of Chesapeake Bay recently measured a sustained wind speed of 63 m.p.h. (101 km/h) and a wind gust of 77 m.p.h. (124 km/h).
Tropical Storm Isaias will move rapidly toward the north-northeast during the next 24 hours. The center of Isaias will pass west of New York City later today. Tropical Storm Isaias will gradually weaken, but it could bring tropical storm force winds to the northeastern U.S. Wind shear in the lower levels of Tropical Storm Isaias’ circulation is contributing to the spin up of tornadoes. Isaias will drop locally heavy rain and flash floods could occur.
Tropical Storm Isaias will take a track similar to the tracks taken by Hurricane Irene in 2011 and Hurricane Isabel in 2003. Hurricane Irene was similar in strength and a little bit larger than Isaias when it hit North Carolina in 2011. Irene was already weakening when it hit the coast while Isaias was strengthening at landfall. According to the Tropical Cyclone Report on the National Hurricane Center’s (NHC) website, Hurricane Irene caused 15.8 billions dollars of damage in the U.S.
Hurricane Isabel was larger and stronger than Isaias was when it made landfall in North Carolina. Isabel was also weakening at the time of landfall. According to the Tropical Cyclone Report on NHC’s website for Hurricane Isabel, it caused 5.4 billion dollars of damage in the U.S.
