What to do now

Follow official instructions on whether to shelter in place or evacuate.
If told to shelter, go in with pets, close windows and doors, and switch off fans and AC.
Take medicines, phone and charger to your safe room and tape plastic over windows, vents and door gaps.
Use towels or clothing to block gaps if you have no plastic sheeting.
If exposed outdoors, move away from the area and upwind if you can.
Do not rely on a car for protection, as vehicles are not airtight.
If evacuating, take your kit and use the route officials give, with no shortcuts.
Do not smoke, eat or drink if you may be contaminated.
