Trudy strengthened to a category ۲ hurricane as it moved toward Mexico’s south-western and west-central Pacific coast on Saturday, the US National Hurricane Center said.
A hurricane warning was in effect from Manzanillo in Colima state to Cabo Corrientes in Jalisco. The latest NHC data showed Trudy with maximum sustained winds of ۱۰۰mph (۱۵۵km/h) and about ۲۰۵ miles (۳۳۰km) south/south-east of Cabo Corrientes and ۱۱۵ miles (۱۸۰km) south/south-west of Manzanillo, moving north-west at ۱۰mph (۱۷km/h).
Meanwhile, Typhoon Champi strengthened into a category ۴ weather system as it moved toward Guam.
Trudy’s center was expected to approach the Mexican coast on Saturday and pass near it into Sunday. After the latest warning, Mexico’s government issued a tropical storm warning for Las Islas Marias and discontinued a similar warning for its coast south of Lazaro Cardenas.
The Mexican navy urged mariners and coastal residents to exercise extreme caution because of high waves, heavy rain and the risk of rising rivers, flooding and landslides in vulnerable areas.
Colima authorities said the risks remained low, but warned that heavy rainfall could cause damage because the ground was already saturated by successive storms along the Pacific coast.
Trudy was expected to bring ۴-۸in (۱۰-۲۰cm) of rain through the weekend, with isolated totals of about ۱۵in (۳۸cm).
Also in the Pacific, Champi strengthened into a category ۴ storm as it moved west toward Guam at ۱۵mph (۲۴km/h).
By Saturday night local time, Champi was about ۲۵ miles (۴۰km) south-east of Guam, with maximum sustained winds of ۱۴۰mph (۲۲۵km/h), according to the US National Weather Service.
The storm was forecast to pass south of Guam early Sunday local time and continue intensifying through the day. Guam and Rota remained under a typhoon warning, while Tinian and Saipan were under a tropical storm warning and typhoon watch.
The governors of Guam and the Northern Mariana Islands both requested emergency disaster declarations on Friday. Approval by Donald Trump would authorize federal support and funding for emergency protective measures.
Airports, harbors and some health facilities in the territories were closed. Resources were unlikely to reach the islands for three to five days, according to Saturday updates from the Federal Emergency Management Agency.
The territories are still recovering from Super Typhoons Sinlaku and Bavi, which struck in April and July, respectively.
