With Supertyphoon Francisco moving farther away from the Marianas and a tropical depression passing northeast of the CNMI yesterday, it is possible that up to three more storms or typhoons could pass or hit the Marianas until December.
National Weather Service meteorologist-in-charge Genevieve Cruz-Miller told Saipan Tribune that the months of October, November, and December are typically active times for tropical cyclone development.
“With this in mind, we are likely to see one to three additional threats to the islands,” said Cruz-Miller in an email.
As of 1pm yesterday, the National Weather Service said that the center of Supertyphoon Francisco was 540 miles west of Agrihan, 580 miles west-northwest of Saipan, and 575 miles northwest of Guam.
With maximum sustained winds of 160 miles per hour, Supertyphoon Francisco is moving west-northwest at 8 mph toward Okinawa.
Meanwhile, as of 1pm yesterday, the center of Tropical Depression 27W was 300 miles north-northeast of Agrihan, 345 miles north of Pagan, and 550 miles north of Saipan.
Packing maximum sustained winds of 30mph, Tropical Depression 27W is forecasted to remain a tropical depression through Monday, then dissipate over the Pacific Ocean.
On the naming of storms or typhoons, Cruz-Miller said each basin has a list of names provided to the Regional Specialized Meteorological Center for naming tropical cyclones once they reach tropical storm strength.
For the western North Pacific and the South China Sea, Cruz-Miller said, this list is composed of names contributed by the 14 countries associated with the Economic and Social Commission on Asia and the Pacific Typhoon Committee.
“Francisco is one of the names contributed by the USA. Other USA names include Maria, Higos, Omais, Roke, Utor, Matmo, Etau, Aere and Vicente,” she said.
