Downtown L.A. Sees No Rain in November for 1st time in Nearly 30 Years

With just hours left to go in this month — and no precipitation in the forecast for Tuesday — downtown Los Angeles is set to experience its first rainless November in almost 30 years, according to the National Weather Service.

The 11th month of the year is typically not a wet one for the area, with downtown’s average just a hair above three-quarters of an inch on average, NWS said.

A somewhat different viewpoint on the development of drought considers how much precipitation has fallen (or not) and how much is likely to fall in coming months, based on climatology. The following are maps of this and previous years’ drought development that explicitly takes both of these aspects into account.
