Major corridors we watch in California
In California, Snowbirds keeps live conditions on the routes that make or break a long haul:
I-5 over the Grapevine (Tejon Pass)
I-80 over Donner Pass in the Sierra
I-15 over the Cajon Pass
Sierra Nevada snow triggers chain controls on I-80 and US-50 in winter, while dense Tule fog blankets the Central Valley on cold mornings.
What Snowbirds shows on your California route
DOT highway webcams — tap any camera along your corridor and let AI read the pavement: snow-packed, wet, or clear.
511 road reports — closures, crashes, work zones, and winter driving conditions straight from the state's official feed (373 active right now).
NOAA weather alerts — official National Weather Service warnings filtered to your corridor, not the whole state.
Weather radar — live NEXRAD overlay on the same map as your route.
Departure-window optimizer — we simulate leaving morning or afternoon over the next five days and rank your windows against the hourly forecast at every checkpoint.
RV crosswind risk — high-profile vehicle? We flag the segments that can push a rig sideways.
