Flood Watch Issued from 2 p.m. Today Through Friday

Posted at 9:45 a.m.

Flood Watch

The National Weather Service has issued a Flood Watch in effect from 2 p.m. this afternoon through Friday evening for the potential for flooding from heavy rain. Localized areas of flooding of small streams and urban areas are possible today and tonight.

A Flood Watch means there is a potential for flooding based on current forecasts. You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

From 2 p.m. this afternoon through Friday evening, periods of rain will continue across the region. This rain will be heavy at times, with overall additional rainfall totals of 3 to 5 inches. While flash flooding cannot be ruled out, the primary concern is flooding of small streams and low-lying areas. Streams are already elevated and soils saturated from earlier rainfall, increasing the flood threat.

Turn Around Don’t Drown

Flooding is one of the leading causes of weather related fatalities in the U.S. On average, flooding claims nearly 90 lives each year. More than half of these deaths occur in motor vehicles when people attempt to drive through flooded roadways. This happens because people underestimate the force and power of water, especially when it is moving.

  • Just 6 inches of fast-moving water can knock over and carry off an adult.
  • 12 inches of water can float a small car. If that water is moving, it can carry that car away.
  • 18 to 24 inches of flowing water can carry away most vehicles, including large SUVs.

It is impossible to tell the exact depth of water covering a roadway or the condition of the road below the water. This is especially true at night when your vision is more limited.  It is never safe to drive or walk through flood waters.

Any time you come to a flooded road, walkway, or path, follow this simple rule: Turn Around Don’t Drown.
