A winter rain checklist is easier to tackle while the gutters are dry and the power is on.

 

For Napa Valley households, the job includes knowing where to get local help, how to receive warnings, and whether water has a clear path away from the house.

 

Start with the path water takes

 

Napa County’s preparation guidance recommends clearing gutters and private drains where safe and securing loose outdoor items.

 

Look for leaves blocking drainage and note places where water has pooled during past storms.

 

Keep debris out of the street rather than shifting a blockage farther downhill.

 

If a gutter or roof needs work you cannot safely reach, arrange help before wet weather.

 

Renters can report drainage problems to their landlord early, with photos showing where water collects.

 

Find sandbags before you need them

 

The City of Napa’s Sandbag Saturday program offers free sand and bags to city residents and business owners on the first Saturday of each month, November through April.

 

Distribution runs from 8 a.m. to 4 p.m. at 720 Jackson Street, Napa, with a limit of 10 bags per household.

 

It is self-service, so bring gloves and a shovel.

 

Separate emergency distribution may open when flood conditions warrant.

 

Elsewhere in the valley, use the county’s sandbag station directory to reach the relevant city or station and confirm current access before leaving.

 

Some sites open only ahead of major rain; a location on the list does not mean it is open today.

 

Prepare for a disrupted day

 

Ready Napa County also recommends household supplies and plans for medications, mobility needs, medical equipment, and pets.

 

Use its storm resources to sign up for Alert Napa County and give officials more than one way to reach each adult in your household.

 

Charge devices, keep flashlights handy, and agree on how family members will stay in touch.

 

During a storm, follow official evacuation instructions and never walk or drive through floodwater.

 

You do not need a prediction of an unusually wet winter to make these preparations worthwhile.

    Renters should definitely take pictures of pooling water and send them to the landlord before the rain starts.

    The station directory can be confusing. Glad it says to check that a location is actually open.

    Bring your own shovel is an important detail. I would've shown up empty handed.

      Mike T.I would have forgotten the shovel too. Gloves sound worth bringing along as well.

    Ten bags per household is less than I expected. Guess I should get there early.

    Good to know Sandbag Saturday is at 720 Jackson. I always forget where to go.

    Thanks for the reminder. My gutters are full of oak leaves already.
