gusts. Steady weakening is forecast during the next couple of days.
 
Tropical-storm-force winds extend outward up to 320 miles (520 km)
from the center. An observing site on Beaver Island, Canada,

WIND: Tropical storm conditions are occurring along the coasts of 
Maine and Nova Scotia and will spread northward within the Tropical 
Storm Warning areas through tonight.  The strong winds are leading 
to downed trees and power outages.
 
SURF:  Swells generated by Lee are affecting Puerto Rico,
Hispaniola, the Turks and Caicos Islands, the Bahamas, Bermuda, the
east coast of the United States, and Atlantic Canada.  These swells
are likely to cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office.
 
RAINFALL:  Lee may produce an additional 1 to 2 inches of rain, or
25 to 50 millimeters, over portions of eastern Maine and New
Brunswick. This may produce localized urban and small stream
flooding.
 
STORM SURGE: A dangerous storm surge will produce coastal flooding
within the wind warning areas in Atlantic Canada in areas of
onshore winds. Near the coast, the surge will be accompanied by
large and destructive waves.
