8am Update on Major Hurricane Joaquin

Major hurricane Joaquin continues over the central Bahamas this morning… with max winds a dangerous 130 mph… moving slowly to the northwest at 3 mph.

The storm will gradually pull north today… and northeast tonight and pull away from the Bahamas. The storm will move well east of the Coastal Empire and Low Country this weekend… holding on major hurricane status. It will then likely pull between Bermuda and Cape Hatteras and stay over the open ocean Sunday night. It will then stay well offshore the northeast United States and gradually weaken early and mid parts of next week.

So the good news this morning… the core of this system will not impact the eastern United States.

HOWEVER… tropical moisture associated with Joaquin will pull into the southeast states… leading to developing very heavy rainfall over the next couple of days. It will combine with a stalled coastal front… surface low pressure and upper level trough to bring a high risk of flooding through portions of Georgia… the Carolinas and the mid atlantic.

There is the risk for significant rainfall induced flooding in our area over the next couple of days… especially along and north of I-16. For the very latest forecast… radar and information from StormTeam 3… see our weather page at http://www.wsav.com/weather

At 800 AM EDT (1200 UTC), the center of Hurricane Joaquin was

located near latitude 23.4 North, longitude 74.8 West. Joaquin is

drifting toward the northwest near 3 mph (6 km/h). A faster

northward motion is expected to begin later today, followed by a

turn toward the northeast and an increase in forward speed tonight

and Saturday. On the forecast track, the core of the strongest winds

of Joaquin will continue moving over portions of the central and

northwestern Bahamas today. Joaquin will begin to move away from the

Bahamas tonight and Saturday.

 

Maximum sustained winds are near 130 mph (215 km/h) with higher

gusts. Joaquin is a dangerous category 4 hurricane on the Saffir-

Simpson Hurricane Wind Scale. Some fluctuations in intensity are

possible during the next 24 hours. Slow weakening is expected to

begin on Saturday.

 

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

(335 km).

 

The minimum central pressure just reported by an Air Force Reserve

Hurricane Hunter aircraft is 937 mb (27.67 inches).

 

WIND: Hurricane conditions are expected to continue across portions

of the central and southeastern Bahamas through today. Hurricane

and tropical storm conditions are expected over portions of the

northwestern Bahamas today. Tropical storm conditions will affect

other portions of the southeastern Bahamas and the Turks and Caicos

Islands today. Tropical storm conditions are expected over portions

of eastern Cuba through this morning.

 

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.

 

RAINFALL: Joaquin is expected to produce total rain accumulations

of 12 to 18 inches over the central Bahamas with isolated maximum

amounts of 25 inches. Rainfall amounts of 5 to 10 inches are

expected over the southeastern Bahamas, with 2 to 4 inches over the

northwestern Bahamas, eastern Cuba, Haiti, the Dominican Republic,

and the Turks and Caicos Islands. This rainfall could result in

life-threatening flash floods.

 

SURF: Swells generated by Joaquin will affect portions of the

Bahamas during the next few days. Swells have begun to affect

portions of the southeastern coast of the United States and will

spread northward along the east coast of the United States through

the weekend. These swells are likely to cause life-threatening surf

and rip current conditions. Regardless of Joaquin’s track, 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.

 

Next complete advisory at 1100 AM EDT.
