Tropical Storm Alvin was upgraded by the National Hurricane Center (NHC) to hurricane status, making it the first hurricane of the 2018 Eastern Pacific Hurricane Season.
In the latest advisory from the NHC, the center of Hurricane Alvin was located near latitude 17.4 North, longitude 115.4 West. Alvin is moving toward the northwest near 16 mph (26 km/h), and a gradual turn toward the west-northwest with a decrease in forward speed is expected over the next couple of days.
Maximum sustained winds have increased to near 75 mph with higher gusts. A weakening trend is expected to begin by early Friday and the NHC is forecasting that Alvin will become a remnant low on Saturday and should dissipate soon thereafter. Hurricane-force winds extend outward up to 10 miles from the center, and tropical-storm-force winds extend outward up to 45 miles. The estimated minimum central pressure is 992 mb (29.30 inches.)
