Hurricane Irma is currently moving northwestward away from Cuba and making its way toward the Florida Keys. The center of the storm should arrive in the Keys by Sunday morning and will continue to move along the Florida Gulf Coast throughout Sunday and into Monday. This powerful storm will bring dangerous storm surge and destructive winds. In addition to these risks, heavy rainfall will also accompany the storm. Due to the heavy rainfall, a high risk of flash flooding will be possible in the Florida Keys through Sunday morning. In addition to flash flooding, southern Florida is also in a slight risk for severe weather. On Sunday and into Monday morning, the majority of Florida, with the exception of portions of the Florida Panhandle, will have a high risk of flash flooding. Severe weather is also expected on Sunday for most of eastern Florida and extreme southeastern Georgia. By Monday, as Irma weakens to a tropical storm, heavy rainfall is expected in eastern Georgia and southern South Carolina--and with it, a moderate risk for flash flooding. See the National Hurricane Center (www.hurricanes.gov) for the most current information regarding Hurricane Irma. As an upper level low meanders along the California coast, it will bring moisture across the southwestern U.S. This will give way to scattered showers and thunderstorms throughout southern and eastern California, the Southwest and Great Basin in the late afternoon/early evening throughout the short term period. Meanwhile, a cold front will move through the Pacific Northwest by tonight--bringing with it showers into western Washington and northwestern Oregon. However, once the front pushes past the area--the northwestern U.S. will dry out. The eastern and southern U.S. will experience below normal temperatures for the next few days. The West Coast will have one more day of near-normal temperatures; however, by Sunday and Monday, warmer conditions return. In fact, areas along and west of the continental divide will be above normal throughout the short term period in addition to the Plains and portions of the Upper Midwest.
