DISCUSSION AND 48-HOUR OUTLOOK
At 500 AM EDT (0900 UTC), the center of Hurricane Joaquin was
located near latitude 25.2 North, longitude 73.1 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 are 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 estimated minimum central pressure is 945 mb (27.91 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions 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: A very dangerous and life-threatening storm surge will
raise water levels by as much as 6 to 12 feet above normal tide
levels in the central Bahamas in areas of onshore flow. A storm
surge of 2 to 4 feet above normal tide levels is expected in the
remainder of the Bahamas within the hurricane warning area. Near the
coast, the surge will be accompanied by large and dangerous waves.
Water levels should slowly subside today as Joaquin moves away from
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.
