California's mountain ranges influence the climate as well: moisture-laden air from the west cools as it ascends the mountains, dropping moisture; some of the rainiest parts of ...
The Santa Ana winds combined with low relative humidity down to 10% will create several hours of elevated critical fire weather conditions across the region. Under these conditions, a spark could ...
