Because the ground is saturated, much of the rain will run off, leading to flooded streams and roads. Late Monday evening commutes may be affected.
Remember, never drive through flooded areas. Turn around, don’t drown.
Weakened trees may also fall because of saturated soil, and travel delays are possible.
Severe weather is not expected, but an isolated damaging wind gust is possible.
