Guam – No fireworks expected for our Fourth of July this year due to serious weather conditions in our region. A storm is brewing and is on its way to the Marianas, currently tracking West at 12 mph. The formation that has since been dubbed Tropical Storm 10W is anticipated to intensify through Thursday.
Located just 155 miles Southeast of Guam and 180 miles South-southeast of Rota as of this morning, the National Weather Service has since issued Tropical Storm Warnings for both islands, which are much closer to the center of what is now being called Tropical Storm 10W. Tropical Storm Watches have also been issued for Tinian and Saipan, which are much further north.
The tropical storm warning for Guam and Rota means storm conditions like heavy rainfall and damaging winds of 39 miles or more are anticipated to reach the area within 24 hours, however because of Guam’s closer proximity to the center of Tropical Storm 10 W, those weather conditions is expected as soon as tonight.
The tropical storm watch issued for Tinian and Saipan means similar storm conditions are also expected, however much later than of a storm warning. In fact, the National Weather Service is giving the two islands 24 to 36 hours before such intensifying weather will reach the area.
The center of Tropical Storm 10W has been located near Latitude 11.7 N and Longitude 146.2 E, currently moving W at 12 mph. However, it is anticipated to shift Northwestward with a decrease in forward speeds in the next 24 hours, which puts 10W on track over Guam or through the Rota Channel. Following its current track, weather conditions are also expected to intensify by tonight for Guam and Rota, and by Thursday for Tinian and Saipan.
