Western North Carolina will be receiving several inches of rain over the next few days as the remnants of Tropical Storm Lee pass over our area. Forecasts range from 3 inches to over 10 inches. Stay tuned to the National Weather Service for up to date information and your favorite local media outlet for specific road and business closures that will undoubtedly arise from this storm dumping so much rain on us in such a short period of time. You can keep an eye on conditions in western North Carolina via this Weather Dashboard provided by the GSP Office or you can watch real time GRLevel III Radar Data at a special page on Dacula Weather. I will be posting updates on this blog and via Twitter as the situation warrants and I continue to have access to the Internet. I will be out and about Tuesday afternoon and evening gathering photos and video of local flooding and the planned meeting of the Franklin Town Board of Aldermen at 7pm.
Here is a screenshot I took in Google earth of a model run displaying probable rain totals for the next 5 days this morning for western North Carolina:
As you can see, it looks like the most rain will probably fall in an area encompassing most of Macon and Jackson Counties and continuing in a northeasterly direction from there for the next 50 or so miles. This is where at least 8 inches will fall. The official NWS forecast for my location 4 miles northeast of Franklin, NC calls for 6 to 10 inches over the next 3 days. The National Weather service has already instituted a Flash Flood Watch for the entire area to alert people to the developing weather hazard that will include flooding and potential mudslides. I remind you of the mudslide that killed 4 people in the Peeks creek Community after the remnants of Hurricanes Frances and Ivan passed over our area.
