Here's what Rabanco has to say about picking up garbage when snow strikes:

When the snow falls ... Here’s what to expect:

On your next regularly scheduled collection day, up to twice the regular amount of garbage will be collected for no additional charge. Billing credits will not be issued for delayed collection due to inclement weather.
