.DISCUSSION...
Hello, Amy! At the time of this writing, rain showers are moving
over the burn site. The chance for showers will decrease to near-
zero through the remainder of the evening. Patchy fog is likely
overnight and early tomorrow (Wednesday) morning given forecasted
relative humidity maxing out at 100% and light to calm winds.
Transport winds tomorrow will start out north-northwest and
gradually shift to north-northeast through the afternoon.
Transport wind speeds will be 6-11 mph through early afternoon,
then decrease to 6 mph or less through the remainder of the

tomorrow.
