 Monthly Summary 

          A generally fair and mainly dry weather pattern prevailed across the local islands during the first two weeks of February with just passing showers along the north and east coast of Puerto Rico as well as over the U.S. Virgin Islands. This pattern of limited low level moisture and stable conditions helped to suppress significant afternoon convection across Puerto Rico. By mid-February, afternoon showers were noted each day across the interior and west sections of Puerto Rico due to diurnal heating combined with an increase in low level moisture and enough upper level dynamics. The remainder of February was dominated by a return to high pressure ridge and its associated fair weather pattern across the local islands.
