be rained in

To be forced to remain inside because it is raining outside. I was looking forward to our company barbecue, but it looks like we might get rained in. The dogs hate it when they're rained in and can't run around outside like mad periodically throughout the day. What are we going to do if we're rained in? This house isn't big enough to hold all the people who said they're coming!
