OCTOBER 2000 Wx Review

Officially, eight days of rain >.01", two other .01" days actual rainfall (as compared to coastal drizzle which oftentimes accumulates generally a hundredth or two, but can occassionally get to .10" with higher dew points). By any measure, an unusually cool and frequently wet October. Jly-Jun rainfall to date is now over 4", about 50% greater than normal. While it would not be uncommon to have little or rain by now (this season), we have had wet Octobers before. In some cases, October rains are associated with cut-off lows that get parked (lost) next to the West Coast, and as such become capable of flinging moist tropical up the coast..and such was the case this year.
