ABC News Chief Meteorologist Ginger Zee flew with NOAA researchers to the center of Hurricane Lee to collect data on the storm.
Lee, now a Category 2 hurricane, is bringing big waves — up to 12 feet — to the entire East Coast.
A tropical storm warning is in effect for Bermuda, where Lee will bring strong winds and heavy rain on Thursday.
By Friday, Lee will leave Bermuda and begin pounding New England, where a hurricane watch has been issued for Maine.
Strong winds of up to 60 mph could reach Cape Cod, Massachusetts by Friday night.
On Saturday, wind and rain will spread across the rest of New England. Wind gusts up to 60 mph are possible in Boston Saturday morning.
Heaviest rainfall — 1 to 3 inches — will be from Cape Cod to Bar Harbor, Maine.
Landslides are expected Saturday night in Canada, New Brunswick or Nova Scotia, near the Maine border. By then Lee will have weakened to an extra tropical storm system, but strong winds will continue into Maine and Canada into Sunday morning.
