ZCZC MIATCDEP4 ALL TTAA00 KNHC DDHHMM TROPICAL STORM SIMON DISCUSSION NUMBER 23 NWS NATIONAL HURRICANE CENTER MIAMI FL EP192014 200 AM PDT TUE OCT 07 2014 The cloud pattern of Simon consists of a tight swirl of low clouds with some patches of convection to the northeast of the center. A recent ASCAT overpass indicated that there are 35-kt winds associated with the circulation. These winds were primarily occurring to the southeast and northwest of the center. A strong shear is forecast to remain over the cyclone, and Simon is expected to become a post-tropical cyclone in about a day, and then dissipate over the rugged terrain of Baja California peninsula. Simon is moving toward the north-northeast or 015 degrees at 6 kt. The cyclone is already embedded within the mid-latitude southwesterly flow and this general motion should continue until dissipation. The NHC forecast is very close to the multi-model consensus. Even if Simon or its remnant circulation does not make it across the rugged terrain of the Baja California peninsula, moisture associated with this system is expected to spread across the northern Baja California peninsula, northwestern Mexico, and into the U.S. Desert Southwest, which could trigger heavy rains in those regions during the next few days. Please refer to statements from your local weather office for information on hazards specific to your area.
