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.
