* OUTFLOW WINDS...Any storms that develop will be capable of
gusty and erratic outflow winds between 20 and 30 miles per
hour. Outflow winds can occur ahead of and behind storms and
cause erratic wind directions.
* IMPACTS...Scattered lightning in dry fuels can cause multiple
fire starts. Thunderstorms can also bring sudden sharp wind
shifts on existing fires, causing rapid changes in a fire's

winds can be a threat for several hours following the start of
a new lightning-caused fire. If a fire were to begin, air
quality may diminish in the surrounding area.
