. Sam is forecast to become a major hurricane
— 类别 3 或更高 — by Saturday afternoon
Sam started the day Thursday with winds of
35 mph and ended the day at
70 英里每小时, signifying a rapid intensification
, which occurs when a tropical cyclone strengthens by at least
35 英里每小时 24 小时.
Moving to the west at 15 英里每小时, Sam is approximately 1,470 miles east-southeast of the northern Leeward Islands, churning in open seas. Impacts from the storm, 然而, may be felt next week.
Over the next five days, Sam will move toward the Leeward Islands and turn slightly northward as it approaches the islands.
“What is not clear at this point is what impacts it will have on land,” CNN meteorologist Dave Hennen said. “马上, it looks like it may pass north of the Leeward Islands and Puerto Rico early next week, but that could change.”
Noting what long-range computer models are showing, Hennen said, “Places like Puerto Rico, the Virgin Islands, Bahamas, Bermuda and even the East Coast of the US need to watch the storm closely over the next week. The models don’t currently agree where the storm is headed, but do agree that it’s likely to be a powerful hurricane.”
