Guam – As PNC concluded our interview at National Weather Service today shortly before 1PM, computers started beeping, and Yutu was upgraded to a Super-typhoon. According to NWS Chief Meteorologist Chip Guard, Super-typhoon Yutu is anticipated to make an impact anywhere around Saipan and Tinian. While the eye of the storm will not be making a direct impact to Guam, the island is anticipating 4-6 inches of rain as well as 40-60 miles per hour winds around midnight. The NMI is anticipating 10-14 inches of rain and while Rota will be receiving 80-90 miles per hour winds, Saipan and Tinian could receive 130-150 miles per hour winds.
Guard points out that, while Guam will not be receiving the brunt-force of Yutu, residents should still take precautions as the some of the effects of Yutu will still be apparent on Guam. Some of the effects include peripheral winds, waves and possibly some of heavy rains.With regards to waves, Guard highlights that when water comes over the reef, it has to go back out into the open ocean creating very strong rip currents. If one were to get caught in one of those, they will be carried out to sea.
The Governor declared COR 1 for Guam at 5 pm today. Super-typhoon Yutu was originally anticipated to make its closest point of impact a 5 am Thursday morning. That timeline has been moved up to around midnight today. Yutu is going through a process of rapid-intensification. This means the storm is developing much faster than the normal rate of intensification. A storm could start off at 65-75 miles-per-hour and end up at 170 miles-per-hour. Guard also confirmed that Yutu has the potential to be as strong, if not stronger, than typhoons Pongsona and Paka.
Meteorologist Chip Guard reminds us that even though the Closest Point of Approach is at midnight, residents should heed government warnings and stay indoors until the all clear is given. The Closest Point of Approach simply means that the storm is as close as its going to get and is going to move away. Frequently, the worst part of the storm is on the back side of the storm. The latter part of a storm tends to last longer. The conditions are more severe and extend farther out on the east side than they do on the west.
