An eyewall replacement cycle has impacted Super Typhoon Bavi, expanding the wind field and growing the typhoon to a size the U.S. Joint Typhoon Warning Center described Thursday as “gargantuan.”

The wind field of Bavi is in the top three percent of all typhoons in the Western Pacific in the last 10 years, according to the FOX Forecast Center, though the maximum sustained winds of the storm have gotten weaker since its expansion.

Experts expect Bavi to continue weakening, graze northern Taiwan, and make landfall in China by Saturday, likely causing flash flooding and landslides.

Bavi hammered U.S. territories Guam and the Northern Mariana Islands on Monday afternoon, unleashing 180mph winds that caused widespread power outages, the forecast center reported.
