Flood watch issued for SLO County as remnants of tropical storm hit California
Part of San Luis Obispo County will be under a flood watch Wednesday evening as heavy thunderstorms are expected to sweep across the area.
According to the National Weather Service, “flash flooding caused by excessive rainfall is possible” across much of Southern California and into the Central Coast, including San Luis Obispo County interior valleys and mountains.
Rain rates during the storm could exceed half-an-inch per hour, the Weather Service warned.
This could cause flooding of rivers, creeks, streams and other low-lying and flood-prone locations, according to the alert.
The watch is expected to last through late Thursday night.
The potential flooding comes as Tropical Storm Mario moves moisture across California late Wednesday through Friday. The region will have a higher chance of thunder and lightning during the storm.
