Local Flooding Possible Wednesday Night Through Thursday

A Flood Watch covering Pasadena and surrounding foothill communities, including Altadena, will be in effect from Wednesday evening through Thursday evening, according to a bulletin issued Tuesday by the National Weather Service in Los Angeles/Oxnard.

In its bulletin, the NWS reports that “a strong winter storm will bring moderate to heavy rainfall to the area Wednesday night and Thursday.”

Forecasters note that “antecedent conditions from last week’s rain” combined with the expected rainfall totals and intensities “could generate some significant hydrologic impacts.”

The bulletin adds that “debris flow are possible near recent burn scars” and warns of “a high risk of rock and mudslides in the canyons.”

The agency also states that “those living in areas prone to flooding should be prepared to take action should flooding develop.”
