 Barrel came ashore as a Category 1 hurricane, bringing howling winds and torrential rain that brought down trees and flooded streets in the Houston area. According to the tracking website PowerOutage.us, Barrel cut electricity to more than 2.7 million homes and businesses in Texas. While the vast majority were in Texas, there were plenty of outages in Louisiana as well. And while the lights have begun to come back on, officials say it may take several days to fully restore power.
