Typhoon Cimaron (2018)

In the Mariana Islands, a tropical storm warning was put in effect for the islands Saipan and Tinian. Meanwhile, a hurricane warning was issued for the islands of Agrihan, Pagan, and Alamagan.[7] 18 people stayed at 4 shelters in Saipan and Tinian, while a liaison officer was sent to the former to help response efforts.[8] Public schools and government offices were forced to shut down on the islands of Saipan and Tinian. However, schools remained open on Rota.[9] As Cimaron dumped several inches of rainfall over the Northern Mariana Islands, a flash flood watch was put in place for Saipan, Tinian, Alamagan, Pagan, and Agrihan. Widespread flash flooding was reported with the worst being in Saipan where numerous roads were flooded.[10] Heavy rainfall peaked at 8 in (203.2 mm) in Saipan.[11] A couple of days after Cimaron affected the Mariana Islands, the clearing of floodwaters began in Saipan.[12]
