ZCZC MIATCDEP2 ALL TTAA00 KNHC DDHHMM HURRICANE BLANCA DISCUSSION NUMBER 28 NWS NATIONAL HURRICANE CENTER MIAMI FL EP022015 900 AM MDT SUN JUN 07 2015 The satellite presentation of Blanca continues to deteriorate, with the eye no longer visible and the coverage and intensity of deep convection diminishing. The current intensity is set at 80 kt which is a blend of Dvorak T and Current Intensity numbers. An Air Force Hurricane Hunter aircraft should provide a good estimate of the intensity in a few hours. Under the influence of progressively cooler sea surface temperatures, southerly vertical shear, and the terrain of the Baja California peninsula, the cyclone should continue to weaken quickly. The official intensity forecast is close to the intensity model consensus and calls for the system to weaken to a tropical storm within 12 to 24 hours. Blanca will likely degenerate to a remnant low within a couple of days. The initial motion estimate, 340/10 kt, is about the same as in the previous advisory. Blanca should continue to move along the western periphery of a mid- to low-level ridge until dissipation. The official track forecast is very similar to the previous one and also very close to the dynamical model consensus. Moisture associated with the remnants of Blanca is expected to affect portions of the southwestern United States later this week.
