The United States may have never experienced a storm like Harvey. With forecasts of up to and maybe more than 50 inches of rain, the people of Texas and the Gulf Coast are experiencing what has been described as epic floods.

Americans are responding overwhelmingly, but Harvey also reminds us that flooding can occur anywhere. In fact, Pennsylvania is the most flood-prone state in the country.

On Tuesday's Smart Talk, we focus on Harvey and flooding.

We'll speak with Rachel Bracken, a former Lancaster County resident, who now lives outside Houston.

How does the nation's most flood-prone state prepare for flooding when there is a significant rain event and what of kind of challenges does that present? Pennsylvania Emergency Management Agency Director Richard Flinn appears on the program to explain.

There always are a lot of questions about flood insurance, what it covers when there is water damage, who should purchase flood insurance and what does it cost? Ron Ruman, a spokesman for the Pennsylvania Insurance Department answers those questions.

We also hear from the American Red Cross of Central Pennsylvania about what assistance is needed in the flood zone.
