DISCUSSION AND 48-HOUR OUTLOOK
At 800 AM EDT (1200 UTC), the eye of Hurricane Joaquin was located
by a reconnaissance plane near latitude 25.6 North, longitude 72.5
West. Joaquin is moving toward the northeast near 13 mph (20 km/h),
and this motion is expected to continue through tonight with an
increase in forward speed. A turn toward the north-northeast is
forecast on Sunday. On the forecast track, the center of Joaquin
will continue to move away from the Bahamas today, and pass west of
Bermuda on Sunday.
Maximum sustained winds remain near 125 mph (205 km/h) with higher
gusts. Joaquin is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Slow weakening is forecast to begin later
today, followed by steadier weakening Sunday and Sunday night.
Hurricane force winds extend outward up to 50 miles (85 km) from the
center and tropical storm force winds extend outward up to 205 miles
The minimum central pressure just reported by an Air Force
reconnaissance plane was 940 mb (27.76 inches).
HAZARDS AFFECTING LAND
WIND: Gusty winds will continue to affect portions of the central
and southeastern Bahamas this morning. Tropical storm conditions are
first expected to reach Bermuda by Sunday morning, with hurricane
conditions possible by Sunday afternoon.
STORM SURGE: Water levels should slowly subside today as Joaquin
moves away from the Bahamas.
RAINFALL: Joaquin is expected to produce additional rain
accumulations of 2 to 5 inches over the Bahamas, eastern Cuba,
Haiti, the Dominican Republic, and the Turks and Caicos Islands
through today. Isolated maximum storm-total amounts of 25 inches are
possible in the central Bahamas. Outer rain bands of Joaquin will
begin to affect Bermuda by early Sunday, and Joaquin is expected to
produce 3 to 5 inches of rainfall over Bermuda through Monday. This
rainfall could result in life-threatening flash floods.
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 coast of the United States and will spread
northward along the east coast of the United States through the
weekend. Swells from Joaquin will begin affecting Bermuda today and
continue through the weekend. 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.
