SPECIAL WEATHER STATEMENT NATIONAL WEATHER SERVICE CHARLESTON WV 342 AM EST Sat Jan 13 2018 WVZ007>011-014>020-027>031-131445- MASON-JACKSON WV-WOOD-PLEASANTS-TYLER-PUTNAM-KANAWHA-ROANE-WIRT- CALHOUN-RITCHIE-DODDRIDGE-CLAY-BRAXTON-GILMER-LEWIS-HARRISON- INCLUDING THE CITIES OF POINT PLEASANT, NEW HAVEN, RAVENSWOOD, RIPLEY, PARKERSBURG, VIENNA, ST. MARYS, BELMONT, PADEN CITY, SISTERSVILLE, MIDDLEBOURNE, TEAYS VALLEY, HURRICANE, CHARLESTON, SOUTH CHARLESTON, SAINT ALBANS, SPENCER, ELIZABETH, GRANTSVILLE, HARRISVILLE, PENNSBORO, WEST UNION, CLAY, SUTTON, GASSAWAY, BURNSVILLE, GLENVILLE, WESTON, CLARKSBURG, AND BRIDGEPORT 342 AM EST Sat Jan 13 2018 Even as colder air was rushing into the area, rapid river and stream rises were occurring overnight. This was in response to one and a half to two and a half inches of rain that fell over the past two days, in addition to snow melt. Some of streams were approaching bankfull, and even some rivers were getting high enough to cause some flooding of the most vulnerable low lying areas along them. There were isolated reports of roads blocked by high water. Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Be especially cautious at night when it is harder to recognize the depth of the water. TRM
