RALEIGH— The National Weather Service Wednesday afternoon issued a tropical storm warning for Johnston County.

A few buildings might experience window, door, and garage door failures. Mobile homes can be damaged, especially if unanchored.

A few roads might become impassable from large debris, and more within urban or heavily wooded places. A few bridges, causeways and access routes might also become impassable.
Scattered power and communications outages, but it will bemore revalent in areas with above ground lines, said the weather service.
The peak rainfall amounts are expected to be 3-6 inches, with locally higher amounts.
Moderate rainfall flooding may prompt several evacuations and rescues. Rivers and tributaries may quickly become swollen with swifter currents and overspill their banks in a few places, especially in usually vulnerable spots.
Small streams, creeks, and ditches could overflow. Flood waters can enter some structures or weaken foundations. Several places may experience expanded areas of rapid inundation at underpasses, low-lying spots, and poor drainage areas.
Some streets and parking lots take on moving water as storm drains and retention ponds overflow. Driving conditions become hazardous with some road and bridgec losures.
