SAM EXPECTED TO REMAIN A POWERFUL HURRICANE FOR SEVERAL MORE DAYS

According to the NHC Advisory 22…Sam is moving toward the northwest near 9 mph (15 km/h), and this motion is expected to continue for the next few days, with an increase in forward speed beginning on Thursday. A turn to the north is expected by Friday. On the forecast track, Sam will pass well to the northeast of the northern Leeward Islands Wednesday and Thursday. Data from a NOAA Hurricane Hunter plane indicate that maximum sustained winds remain near 120 mph (195 km/h) with higher gusts. Sam is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. The hurricane could strengthen some overnight, and Sam is anticipated to be a category 3 or 4 hurricane for the next several days. Hurricane-force winds extend outward up to 40 miles (65 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km).

HAZARDS AFFECTING LAND

SURF: Swells generated by Sam will reach the Lesser Antilles today and impact these islands for the next several days. Swells are expected to reach Bermuda and the Bahamas mid-to-late week, and then spread to the United States east coast late this week. These swells could cause life-threatening surf and rip current conditions.

 

A well-defined low pressure system associated with the remnants of Peter is located a few hundred miles east of Bermuda. Although shower and thunderstorm activity is currently disorganized, environmental conditions are expected to remain marginally conducive for a short-lived tropical depression to form tonight or Tuesday while the system moves northeastward at about 10 mph. By Wednesday, however, conditions are expected to become unfavorable for further development.

* Formation chance through 48 hours…medium…60 percent
* Formation chance through 5 days…medium…60 percent

 

A broad area of low pressure located several hundred miles southwest of the Cabo Verde Islands is producing a large area of disorganized showers and thunderstorms. Environmental conditions are conducive for further development, and a tropical depression is likely to form during the next day or two while the system moves westward to west-northwestward at 5 to 10 mph over the central tropical Atlantic.

* Formation chance through 48 hours…high…70 percent
* Formation chance through 5 days…high…90 percent

>>> A tropical wave located just offshore the west coast of Africa continues to produce a large area of disorganized showers and thunderstorms. Upper-level winds are conducive for gradual development, and a tropical depression is likely to form in a couple of days while the disturbance moves westward to west-northwestward at 10 to 15 mph over the far eastern tropical Atlantic.

* Formation chance through 48 hours…high…70 percent
* Formation chance through 5 days…high…90 percent
