WIND: Strong winds are possible over portions of Atlantic Canada
and eastern New England this weekend.

RAINFALL: Rainfall will be diminishing across Bermuda today. An
additional inch or less of rainfall is possible.

For portions of New York and New England, and Southeast Canada,
rainfall amounts of 1 to 3 inches, with local maximum amounts of 5
inches, are expected this weekend. Isolated to scattered instances
of urban and flash flooding will be possible.

SURF: Large swells will continue to affect Bermuda for the next
few days. Swells are also affecting portions of the southeastern
U.S. coast and will spread northward along the east coast to
Atlantic Canada during the next couple of days. These conditions
are likely to cause life-threatening surf and rip currents. Please
consult products from your local weather office.
