What the National Weather Service wrote

PR-31 near PR-53 exit 22 impassable due to Rio Blanco out of its banks. The USGS sensor reported 7.91 feet at 7:30 AM AST.

The wider storm

Mid- to upper-level short wave troughs, a jet streak near the region and above normal moisture being steered from the Caribbean resulted in moist and unstable conditions. Available moisture, diurnal heating, local sea breeze convergence, and orographic

effects all also aided in afternoon showers and t-storms. These resulted in Rio Blanco and Rio Grande rising out of their banks and resulting in River Flooding.

Began near Naguabo (18.2121, -65.7779).
