Residents of southern Thailand, particularly those living along the east coast, are being warned of heavy to very heavy rains from Saturday to Monday (December 23-25), which could result in flash flooding, water runoff near foothills, and overflows in low-lying areas.

Florida Governor Ron DeSantis told residents of southwestern Florida to "evacuate now" on Tuesday night as Hurricane Ian drew near, threatening to bring a deadly storm surge and more than a foot (30 cm) of rain to some areas.
