Heavier than expected rainfall Friday with the outer edges of Hurricane Matthew still to come has led the National Weather Service to extend its flash flood watch to the Charlotte area.
Lauren Visin, a meteorologist with the weather service office in Greer, S.C., says forecasters now expect Mecklenburg, Cabarrus, Union counties, along with York County, S.C., to get between 2 and 4 inches of rain before skies clear sometime Saturday afternoon. Isolated areas could get even more.
The flash-flood watch continues through 6 a.m. Sunday. Some isolated flooding surfaced Friday in Union County, Visin said, set off by showers throughout the day.
Wind gusts are still expected to reach 40 mph on Saturday – meaning scattered treefall and power outages are possible.
The heavier rain – fed by the hurricane’s outer edges – will arrive late tonight and continue through midday Saturday, Visin said.
“The key is to know how heavy it will fall. Three inches in 24 hours, we'll be fine. We need the rain. If 3 inches falls in an hour, then we have an issue.”
