Barry was downgraded to a tropical depression over northwestern Louisiana Sunday. But the National Hurricane Center said there's "still a high risk of flash flooding" from heavy rain as it churns toward Arkansas, and forecasters issued several tornado warnings.

Details: Louisiana Gov. John Bel Edwards (D) told a news conference Sunday that first responders rescued 93 people, and he said hundreds of thousands were without power following the storm.

When the next "Big One" hits, the U.S. Geological Survey really hopes you'll pay attention to the alert on your phone.

Why it matters: The ShakeAlert system, installed along the West Coast, can provide anywhere from seconds up to a minute of warning to areas outside the epicenter that a big quake is on the way.
