#727137 (Received by flhurricane at: 9:28 AM 27.Oct.2014) TCDAT4 TROPICAL STORM HANNA DISCUSSION NUMBER 6 NWS NATIONAL HURRICANE CENTER MIAMI FL AL092014 1100 AM EDT MON OCT 27 2014 Deep convection associated with the remnants of Tropical Depression Nine have persisted and become better organized since yesterday. In addition, ASCAT data from overnight indicate that the system was producing 30-35 kt winds to the west of the center, just off of the coast of Nicaragua. Therefore, advisories have been re-initiated, with the system being upgraded to Tropical Storm Hanna. The center of Hanna is very close to the coast of northeastern Nicaragua. The system is moving west-southwestward, or 250/6 kt, and should be inland over Nicaragua by this afternoon. A similar motion should continue for the next 24 hours or so, with the cyclone dissipating by late Tuesday. The main hazard associated with Hanna will be very heavy rainfall. Hanna could produce 10 to 12 inches (250 to 300 mm) of rain, with isolated maximum amounts of 15 inches (400 mm), across Honduras and northern Nicaragua. These rains will likely produce flash flooding and mud slides. Since Hanna is so close to the coast and about to move inland, this forecast advisory was sent a couple of hours earlier than usual to expedite the release of forecast information. An intermediate advisory will be issued at 2 PM EDT, followed by a full advisory at 5 PM EDT, as scheduled.
