Governor Eddie Calvo and Rear Adm. Shoshana Chatfield, commander, Joint Region Marianas, anticipate placing Guam and the respective military bases in Condition of Readiness (COR) 3 at 7 p.m. this evening. At COR 3, damaging winds of 39-57 mph are expected within 48 hours. Please keep in mind, we anticipate the onset of damaging winds as early as Monday night so we are urging the community to take the weekend to prepare. Additionally, the National Weather Service is anticipating issuing a typhoon watch for the Marianas this evening. A typhoon watch means typhoon strength winds of at least 74 mph are possible within 48 hours. Weather conditions could change so it is important to have the most updated information. The Joint Information Center will continue pushing information about the storm as it gets closer. Closest Point of Approach As of 2 p.m., Tropical Storm Mangkhut was located 13.7 degrees north latitude and 161.5 east longitude; about 1125 miles east of Guam, with maximum sustained winds of 40 mph. The tropical storm will continue its westward track and is expected to intensify, possibly becoming a Category 4 typhoon by the time it reaches Guam, with Tuesday 11 a.m. being its anticipated closest appoint of approach (CPA). It is important to still prepare for worst-case-scenario, of a Category 5 typhoon.
Category 4 Typhoon is referred to as a “Very Strong Typhoon” with maximum sustained winds of 130-156 and peak gusts of 165-198 mph.
Category 5 Typhoon is referred to as a “Devastating Typhoon” with maximum sustained winds of 157-194 mph and peak gusts of 199-264 mph. A Category 5 typhoon has the ability to be life-threatening to those that do not prepare in advance.
Although the storm’s CPA is forecast for noon on Tuesday, Guam and the Marianas can expect damaging winds of 39 mph or more as early as Monday around 11 p.m. Don’t Wait - Use Today and Tomorrow to Prepare Upon completion of the following preparedness tips, it is important to take pictures of your home and around property before the storm approaches.
