Showers and thunderstorms associated with the outer bands of Hurricane Sandy were strong enough to produce moderate to major flooding across the Guayanilla and Caguas area between October 25th and October 27th. Moderate and major flash flooding was reported as high intensity rainfall butted up against the Cordillera Central Mountains of Puerto Rico.
