More than a day after Florence's eye passed through southeastern North Carolina, a slower, and potentially more destructive threat emerged: pounding rains and a storm surge that pushed rivers over their banks, overflowing into small inland towns.
Rainfall also is swelling waterways: Meteorologist Ryan Maue of weathermodels.com calculated that 34 million people in the US are forecast to get at least 3 inches of rain from Hurricane Florence, with more than 5.7 million people probably getting at least a foot of rain.
