This impressive storm dumped two inches of rain in the Los Angeles area
on February 25th and 26th, 2004. Some newspapers called it the strongest
winter storm of the decade. Since it had
rained almost two inches just four days earlier, flooding
and mudslides were widespread.
The winds were generally from the south before the cold front passed
and then from the west-northwest after the cold front passed.
But the temperatures didn't change much at all with
this wind shift. This is largely
due to the huge influence that the Pacific ocean has on the
weather in southern California. Weather
systems form and travel over miles of mild ocean waters with
endless amounts of moisture and moderating
temperatures. Here is a table of the weather conditions
from the same period as the satellite images.
