Hurricane Hermine has made landfall near the Big Bend of Florida early this morning is expected to weaken to a tropical storms as it moves farther inland. Check the National Hurricane Center for the most updated information about Hurricane Hermine (www.nhc.noaa.gov). The big bend of Florida can expect heavy rainfall and gusty winds as the storm moves northeast into Georgia early Friday morning. There is a high risk of excessive rainfall across this region through this morning as several inches of rain is expected to fall due to Hermine - significantly elevating the threat of flash flooding. Tropical Storm Hermine is forecast to reach the coastal Carolinas by Saturday morning and will parallel the coast into next week. Heavy rainfall and a threat of flash flooding can be expected for the eastern Carolinas into Saturday morning. Portions of the Mid-Atlantic will get ample rain from the wrap around bands associated with the low pressure center. Three day totals of 3 to 10 inches will be possible from Georgia to southern New Jersey; with isolated amounts of 12+ inches likely. Cooler air will overspread much of the Mid-Atlantic and Southeast regions as a Canadian high pressure slides in behind a southward advancing cold front. The front will slow and even stall as Hermine tracks northeastward across the Carolinas and southern states. The nearly stationary frontal boundary will help maintain continuous rounds of rainfall over northern Florida and the southern Appalachians. Diurnal showers and thunderstorms will be possible across the Southwest and the southern and central Rockies over the next few days. Precipitation totals are expected to be generally less than 0.50 inch - favored higher terrain could observe amounts nearing 1 inch by Monday morning. A low off the Pacific Northwest coast will produce showers and higher elevation snow across the Cascades as cooler air spreads across the northwestern portions of the country behind a strong frontal system. As the weekend progresses, the front will cross the Rockies and traverse through the northern High Plains. Scattered showers will initiate along and ahead of the front. Much cooler air will infiltrate the region. Many locations within the Intermountain West and surrounding Plains will observe a 20 to 30 degree drop in afternoon highs by Monday.
