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.

Near the coast, the surge will be accompanied by large and destructive waves. NEXT ADVISORY ------------- Next complete advisory at 1100 PM AST. $$ Forecaster Kelly/Brown |
