...FLOOD WATCH IN EFFECT FROM 12 PM TO MIDNIGHT TODAY...

.DISCUSSION...

Several rounds of showers (this morning) and thunderstorms are
likely today with a stalled front laying right across the fire area.
Winds are expected to remain out of the northeast through the day
at 8-15 mph. Erratic winds and perhaps a switch to southwesterly
winds may occur between 2-5 PM when the strongest period of storms
are likely to occur. There is a Flood Watch in effect today for the
area with concerns of flash flooding possible in low-lying and flood
prone locations. If smoke is an issue, dispersions will be fairly
low through Monday. No humidity concerns or other significant fire
weather conditions to note.
