Monthly Summary 

        November 2012 began with a southeasterly wind flow across the local islands that produced warm temperatures along the northern coast of Puerto Rico mainly during the first week of the month. The prevailing east northeast wind flow returned around the 10th, and brought periods of morning showers across the local islands as well as limited afternoon convection across western Puerto Rico each day through the rest of the month. Overall a tranquil weather pattern prevailed.
