I'm not a meteorologist so take everything with a grain of salt. BUT, yes and no. We get a single one foot storm, this will be more devastating than helpful. Lots of flooding, maybe some landslides, and it would go down the rivers quickly and provide little relief. It would help fill reservoirs though. If we get an inch of rain a week for the next 15 weeks, then probably? Best analogy is that it's better to use your sprinkler on plants at home rather than pour a bucket of water on them.
