DISCUSSION AND 48-HOUR OUTLOOK
At 500 PM AST (2100 UTC), the center of Hurricane Joaquin was
located near latitude 32.2 North, longitude 66.4 West. Joaquin is
moving toward the north-northeast near 14 mph (22 km/h), and this
general motion with a slight decrease in forward is expected to
continue through Monday. On the forecast track, the center of
Joaquin will pass just west of Bermuda this evening, and pass north
of Bermuda tonight.
Maximum sustained winds have decreased to near 100 mph (155 km/h)
with higher gusts. Additional weakening is forecast during the next
Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 205 miles
(335 km). During the past couple of hours, a 10-minute average wind
speed of 48 mph (78 km/h) and a gust to 64 mph (104 km/h) were
reported at the Bermuda International Airport. On the southwestern
end of the island an elevated site of 290 feet at Harbor Radio, a
10-minute average wind speed of 75 mph (120 km/h) and a gust to 96
mph (154 km/h) were recorded.
The estimated minimum central pressure based on dropsonde data from
a NASA research aircraft is 958 mb (28.29 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions will continue to affect Bermuda
through tonight, with hurricane conditions expected later this
TORNADOES: Isolated tornadoes are possible on Bermuda this evening.
STORM SURGE: A dangerous and life-threatening storm surge is
expected to produce significant coastal flooding in Bermuda. Near
the coast, the surge will be accompanied by large and destructive
RAINFALL: Joaquin is expected to produce total rainfall
accumulations of 3 to 5 inches across Bermuda through tonight.
SURF: Swells generated by Joaquin will continue to affect portions
of the Bahamas during the next few days. Swells are affecting much
of the southeastern and mid-Atlantic coasts of the United States and
will spread northward along the east coast of the United States
through Monday. These swells are likely to cause life-threatening
surf and rip current conditions. Even though Joaquin is expected to
pass well east of the coast of the United States, a prolonged period
of elevated water levels and large waves will affect the
mid-Atlantic region, causing significant beach and dune erosion with
moderate coastal flooding likely. Please consult products from your
local weather office.
