Heavy Rain Threat Continues Through Midweek

Heavy rains have already fallen over parts of eastern North Carolina since Sunday, and more is on the way from Wednesday into Thursday. Flooding will be a concern through at least midweek. Rainfall totals have reached just over 12" in Wilmington since Sunday. Over 10" of that came Monday making for the second highest daily rainfall on record in Wilmington. The highest ever one day rainfall in Wilmington was over 13" during Hurricane Floyd on September 15, 1999. Elsewhere, rain totals since Sunday have reached almost 6" in Fayetteville and 3" in Raleigh. Additional heavy rainfall on top of those totals will cause flooding problems.

Waves of low pressure will move along a stalled frontal boundary near the coast beginning Wednesday. That will spread rain across the eastern half of the state during the day with some of the heaviest rain coming Wednesday afternoon and night. The heavy rain will not only fall along the coast but also across the Triangle and Sandhills. An additional 5" of rain is possible across much of the area through early Thursday, but some locations could see much more than that.

A possible tropical system developing just south of Cuba this morning could add to the heavy rain threat through Thursday and into early Friday. Wednesday and Wednesday night's rain will not be related to this tropical system. This would only serve to add more rain Thursday. Most computer models bring this storm near south Florida Wednesday and then either off the southeast coast or up the Carolina coast Thursday into early Friday morning.
