Image options: [ Enlarge ] [ Full Size ]

Due to a very dry air mass over Yosemite during mid October, fire activity has increased on the NE portion of the Empire fire. Active fire and smoke can be seen from Glacier Point Road. Additional smoke production combined with stable air mass will impact Yosemite Valley during the early morning hours. Normal daytime heating will help clear smoke impacts starting around noon each day.

Current Weather

Weather Concerns

A warming and drying trend will continue through Saturday under a building high pressure system. This will cause the fire to increase activity in heavy pockets of fuel which will produce more smoke and settle into Yosemite's Valleys and drainages at night and into the morning. Smoke will be present until the inversion layer breaks in the morning as temperatures increase.

This warming and drying trend will continue through Sunday and then bring cooler conditions to the district for the early part of next week. No precipitation is expected during this period.
