You're at home, it's been raining heavily all day and a Flash Flood Warning has just been issued.
But, severe weather is also in the area and a Tornado Warning is issued at the same time.
What do you do?
If you haven't lived in a place where multiple severe weather events can happen simultaneously, you've probably never had to make a potentially life-changing decision like that.
But with what seems like an increase in severe weather, choosing to either seek higher ground or head to the basement can seem confusing.
"Weather advisories are issued to keep people safe, and most of the time, they do a good job at that," said Zachary Krauss, of the Alabama Water Institute. "However, sometimes we do have multiple warnings that are issued at the same time, and the instructions contained within can be contradicting."
For example, Krauss said, if there's a tornado warning, there are specific instructions to get into your basement or the lowest level of a structure. Conversely, a flash flood warning has instructions to seek higher ground.
The simplest way to decide what to do is to trust your gut.
"The warnings should encourage people to also use their common sense," Krauss said. "People know their situation the best, and for 90% of people, tornado warnings need to take precedent because they're the most imminent danger. But I encourage you to assess your surroundings and current situation and use your common sense."
Dan Reilly from the National Weather Service in Houston said every situation is different.
"It's hard because sometimes in the heat of the moment, common sense doesn't kick in," he said. "As warning forecasters, we want to minimize that overlap if possible, but people really need to assess their most imminent danger. So, for example, if there's a tornado bearing down they're going to want to take action for that especially if there's no flooding within the home. There really is no set rule for all cases."
Reilly said there have been some changes over the last several years to try and minimize overlapping warnings.
"At the weather service, we really try to be careful with how we draw our warning polygons," he said. "We try to really tighten it into where that tornado threat is and kind of minimize that overlap if we can. And then we want to make sure we sound the all-clear when that tornado threat has passed, so people can then concentrate on the flood hazard."
