What the National Weather Service wrote

Received report of Flood waters about to enter residencies around the intersection of Patricia St and 1st St.

The wider storm

Moisture pulled into the region by TC Tammy (by that time well north of the area), in combination with an upper-level trough, a frontal boundary and a pre-frontal trough, produced numerous showers and thunderstorms across the islands. Between 3 and 7 inches of rain were observed across the northern, eastern, and central portions of Puerto Rico. Several Debris Flow episodes and at least 1 case of wind damage were reported. Swells from Tammy also produced hazardous marine and coastal conditions, resulting in coastal flood in several northern areas.

Began near Guaynabo (18.4020, -66.1255).
