UPDATE: Palomar Observatory is closed to the public today due to the hazardous winter weather conditions.
Be careful out there. Palomar Mountain is currently under a Winter Weather Advisory. Fog, wind, snow and icy roads are expected though at least Thursday morning. Travel to the San Diego mountains is not recommended at this time. If you are planning a trip to the observatory, it might be a good time to put it off for a while.
No word yet if this will affect our weekend tours. I'll post an update later in the week.
Speaking of our tours, here is a nice review of them.
