located near latitude 29.9 North, longitude 67.6 West. Henri is
moving toward the west near 9 mph (15 km/h) and this motion is
expected to continue for another day or so.  A turn to the north is
expected on Friday with that motion continuing into the weekend.
 
Maximum sustained winds have increased to near 70 mph (110 km/h) 
with higher gusts. Little change in strength is forecast during the 
next day or so, but Henri is expected to become a hurricane on 
Friday.
 
Tropical-storm-force winds extend outward up to 80 miles (130 km)
from the center.
 
The estimated minimum central pressure is 995 mb (29.39 inches).
 
 
HAZARDS AFFECTING LAND

SURF:  Swells generated by Henri should continue to affect Bermuda
during the next day or so.  Swells are expected to increase across
much of the east coast of the U.S. and Atlantic Canada later this
week and this weekend. These swells could cause life-threatening
surf and rip current conditions.  Please consult products from your
local weather office.
