Rolling On the Atmospheric River: Another Week of Rain Coming to Pasadena

Another in a series of storms will hit the Southland this week, with rain arriving as early as Sunday and intensifying Monday through Wednesday, forecasters said Saturday.

The weather system will also bring colder temperatures to the area, with daytime highs dropping into the low 60s on Monday and the mid-50s on Tuesday and Wednesday, according to the National Weather Service.

A weak storm system brought a chance of rain to the area late Saturday into Sunday, then a stronger storm system will likely bring heavier rain Monday through Wednesday, the NWS said.

A wind advisory was issued for the region but Pasadena is likely only to experience slight gusting of 10 to 15 mph.

Rainfall totals for Tuesday through Wednesday are expected to be 1 to 2 inches in the San Gabriel Valley.

Dry weather should return by the end of the week, and a warming trend is expected as well.
