The Mariana Islands are experiencing an accelerated transition from the dry to the wet season, with meteorologists warning residents to prepare for a more active weather pattern that includes thunderstorms, heavier rainfall and potential flooding.
According to warning coordination meteorologist Landon Aydlett at the National Weather Service Weather Forecast Office Guam, the region is entering what meteorologists call a tropical upper tropospheric trough.
This is a period when tropical upper-tropospheric troughs create more dynamic weather conditions between May and September.
