5PM Update
The Station Fire is now truly massive. Latest reports estimate the flames have burned through more than 105,000 acres of the Angeles National Forest. The fire zone has more than doubled in size since yesterday.
The winds are picking up, causing worries that the fire will spread toward residential communities to the south and west of the Forest.
Firefighters have set some goals. They're trying to keep the fire west of Highway 39 and the Angeles Crest Highway, and north of the foothill communities from Sunland to Altadena.
New evacuation orders have been issued for residents in Juniper Hills, La Cresenta and Tujunga. Some residents in Altadena are now being allowed to return to their homes.
Air quality remains a concern, with air rated Unhealthy to Hazardous thoughout the West San Gabriel Valley. Meanwhile, the hot weather is expected to continue tomorrow, with a slow cooling trend as the week wears on.
