Tropical Cyclone Update
CURRENT WATCHES / WARNINGS:
Typhoon Warning: Rota, Tinian, Saipan, Alamagan, Pagan, Agrihan
Tropical Storm Warning: Guam
Typhoon Watch: Guam
TC POTENTIAL / HAZARDS:
The tropical storm warnings have been upgraded to typhoon warnings for the Far Northern Mariana Islands of Alamagan, Pagan, and Agrihan. Other than that, no changes have been made to the previous watches and warnings for the CNMI and Guam. Super Typhoon Sinlaku has maintained its northwest course at 7 miles per hour, bringing gusts of 66 miles per hour at Guam and 70 miles per hour at Saipan. It is expected to maintain its course and speed through Wednesday before making a turn to the north, passing through northern CNMI during the latter half of the week. Typhoon-force winds of 130 to 155 miles per hour and 175 miles per hour gusts are forecasted for Tinian and Saipan Tuesday night, while Rota will now see strong tropical-storm force winds of 60 to 70 miles per hour with gusts up to 90 miles per hour around the same time period. Guam’s forecast remains the same of tropical storm-force winds of 50 to 60 miles per hour with gusts of 70 miles per hour through tonight and slightly weakening to 45 to 55 miles per hour on Wednesday. The northern CNMI can expect similar conditions as Tinian and Saipan, possibly stronger as STY Sinlaku continues its trek. Heavy rainfall with locally heavier showers are still possible across the entire region, and seas continue to build to 20 ft.
