On today’s EM Morning Brief, Super Typhoon Sinlaku — a Category 5 storm with 175 to 180 mph winds — is bearing down on the Northern Mariana Islands with catastrophic conditions expected for Saipan and Tinian Monday night. Federal emergency declarations are in place for both Guam and the CNMI. On the mainland, a rare four-day severe weather outbreak continues to threaten Texas, Oklahoma, and Kansas with tornadoes, large hail, and flash flooding. The National Weather Service in Hawaii has extended a statewide flood watch through Monday evening. FEMA has also approved major disaster declarations for Washington state and Oregon following last December’s devastating storms. EM Morning Brief is your concise daily update on national and state-by-state emergency management news. Produced by Sitch Radio, an EOC Voices podcast.
