Super Typhoon Bavi, a storm with the equivalent force of a category-five hurricane, has caused major damage on the US island of Rota in the Pacific. The National Weather Service (NWS) reported that the western eyewall of the typhoon was moving over Rota, with winds reaching 180 miles per hour (290 kilometers per hour). Local authorities have received reports of significant damage from the island's approximately 1,500 inhabitants.
Immediate Impact and Warnings
The NWS issued urgent warnings, advising residents to seek immediate shelter in interior rooms or designated shelters, treating the extreme winds as if a tornado was approaching. Rota Municipal Operations Center's public information officer, Lou Rosario, confirmed that heavy winds and flooding were being experienced, with some residents already reporting major damages. Additionally, some cellphone services were disrupted due to a fallen tower.
Extent of the Storm
NWS meteorologist Landon Aydlett detailed that the entirety of Rota was within the eye of the storm, with maximum winds of 180 mph recorded. Neighboring islands, including Tinian, northern parts of Guam, and the southern tip of Saipan, experienced winds equivalent to a category-one hurricane. Aydlett noted that the storm was leaving the area, with conditions expected to improve gradually.
Previous Storms and Preparations
The Northern Marianas and Guam, collectively home to around 210,000 people, have faced significant storms in the past. Super Typhoon Sinlaku, which hit the region in April, caused widespread devastation. In preparation for Bavi, authorities on Guam warned of potential flash flooding due to eight to 12 inches (20 to 30 centimeters) of rain. The Guam Plaza Hotel, which had previously invested in an $800,000 backup generator after the April typhoon, provided shelter for several hundred people.
Climate Context and Future Risks
The world's oceans experienced their hottest June on record, a factor that can intensify tropical storms and increase moisture, leading to heavier rainfall. The World Meteorological Organization has also warned that El Niño, a natural climate phenomenon that warms surface temperatures in the central and eastern equatorial Pacific Ocean, has begun and is likely to be strong. This could lead to further extreme weather events in the region.
