.DISCUSSION...With increasing moisture and light winds, critical
fire weather conditions will be, at best, localized today and
tomorrow. Scattered to widespread showers and thunderstorms are
expected today and tomorrow, with gusty winds and lightning still
the main concerns. Sunday onward, critical fire weather conditions
are not expected, as widespread showers and thunderstorms are
expected daily, with moderate to heavy rainfall the main concerns.
This does mean an increased concern for burn scar debris flows and
flash flooding in to early next week.
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
