Like last week’s St. Louis flood, the National Weather Service is attributing this flood to thunderstorms, which can cause heavy rains — which can lead to flooding, especially in areas that do not have the infrastructure to protect against floods.

Flood safety tips for St. Louis locals, or anyone in flood-prone areas:

Amidst this St. Louis area flood, the National Weather Service warned locals to avoid driving into flooded areas, noting that most deaths during floods happen in vehicles. Additionally, the CDC advises anyone in an area affected by floods to heed the advice of local authorities, especially when it comes to evacuations; additionally, avoid consuming floodwater or any food or drinks potentially contaminated by floodwater.

And, if you live in the St. Louis area — or any other region prone to floods — the CDC advises putting together an emergency supply kit; making sure you and your family’s full immunization records are stored in a waterproof storage container; and always listening to local news and authorities when rain is expected, so you can adequately prepare your home for the flood, or make arrangements to evacuate your home.
