HURRICANE HUNTER AIRCRAFT FINDS SAM HAS PEAKED IN INTENSITY…EXPECTED TO REMAIN A MAJOR HURRICANE FOR SEVERAL DAYS

According to the NHC Advisory 18…Sam is moving toward the northwest near 7 mph (11 km/h), and this motion is expected to continue for the next few days, along with a gradual increase in forward speed beginning around midweek. Data from the reconnaissance aircraft indicate that maximum sustained winds are near 145 mph (230 km/h) with higher gusts. Sam is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity are expected during the next day or so. Thereafter, slow weakening is forecast. However, Sam is still expected to remain a major hurricane through midweek. Sam remains a small tropical cyclone. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km).

 

>>> Showers and thunderstorms have become a little better organized today in association with a surface trough (the remnants of Peter) located several hundred miles southeast of Bermuda. Upper-level winds are marginally conducive for further development, and Peter could become a tropical depression again during the next couple of days while it moves northeastward at about 10 mph. By midweek, environmental conditions are expected to become unfavorable for further development.

* Formation chance through 48 hours…medium…50 percent
* Formation chance through 5 days…medium…50 percent

 

>>> A tropical wave is expected to move off the west coast of Africa on Monday. Upper-level winds are forecast to be conducive for gradual development thereafter, and a tropical depression is likely to form in a few days while the system moves westward to west- northwestward at 10 to 15 mph over the far eastern tropical Atlantic.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 5 days…high…70 percent

>>> A broad area of low pressure appears to be be forming several hundred miles southwest of the Cabo Verde Islands. Environmental conditions are forecast to support further development of this disturbance, and a tropical depression is likely to form around midweek while it moves westward at 5 to 10 mph.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 5 days…high…70 percent
