A portion of I-80 west has reopened after being shut down for days due to the Floriston Fire.
It's burned 640 acres and is 8% contained, after starting around 10 a.m. on Wednesday northeast of Truckee.
Firefighters are working to strengthen containment lines and limit the fire's spread.
A virtual community meeting was hosted on the Cal Fire Nevada-Yuba-Placer Facebook page on Thursday to provide updates and information about the fire. The meeting can be watched at the Facebook page at this link.
Jeremy Linder with Caltrans said at the meeting that they're working to reopen Interstate 80 and will only do so when it is safe.
Currently crews are working to get concrete barriers to line sections of the interstate to prevent hot rocks and debris from falling onto the roadway.
People are advised not to use Dog Valley Road as a detour, as it is closed as well.
CAL FIRE says it will be using the Castle Peak parking lots at the entrance to Northstar as their Incident Command Post (ICP) for the fire. Do not enter or park in these lots while they are being used for the incident.
At this time, there is no threat to the Northstar area.

Potential power impacts
Tahoe Donner Public Utility Districts says they are monitoring the fire and its potential impact power service in the Truckee area.
While the fire is not currently threatening Truckee, it has the potential to threaten the NV Energy transmission lines that deliver power from Verdi.
If NV Energy opts for an emergency de-energization of the transmission line, all TDPUD customers would lose power without advance notice.
The utility recommends customers take precautions to prepare for the possibility of an outage.
