.DISCUSSION...
Morning clouds and possibly some fog should begin to diminish around
ignition time. Winds will be light and could vary in direction leading
up to the burn period during the early morning hours. By ignition time,
winds should be southerly or southwesterly. Wind speeds will increase
during the afternoon. No significant wind shifts are expected
although some minor backing in wind direction to south-southeasterly
could occur right around sunset. A much windier and drier day is expected
Tuesday and this will lead to rapid fire growth and spread.
