HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are expected to begin over portions

RAINFALL: Heavy rainfall associated with Hermine will remain mainly
offshore through Wednesday. Rainfall totals of 1 to 2 inches are
possible across far southeastern Massachusetts, including Cape Cod
and the offshore islands.
SURF: Large waves generated by Hermine will affect the U.S. east
coast from the mid-Atlantic states and expand northward along the
coast of southern New England through Monday night. These waves are
likely to cause life-threatening surf and rip current conditions,
and significant beach erosion. Please consult products from your
