ZCZC MIATCDEP4 ALL TTAA00 KNHC DDHHMM TROPICAL STORM CELIA DISCUSSION NUMBER 29 NWS NATIONAL HURRICANE CENTER MIAMI FL EP042016 200 PM PDT WED JUL 13 2016 Deep convection associated with Celia has practically vanished, and consequently the Dvorak subjective and objective T-numbers have continued to decrease. However, the cyclone still has a vigorous circulation, and the best estimate of the initial intensity is 45 kt. The circulation of Celia is moving over waters of about 24 degree Celsius and cooling, while the wind shear is forecast to gradually increase. These conditions will result in additional weakening, and Celia is expected to degenerate into a tropical depression in about a day, and into a remnant low soon thereafter. The NHC forecast is following SHIPS guidance. The cyclone appears to be moving toward the west-northwest or 300 degrees at 11 kt around the periphery of the subtropical ridge. Given that Celia is already weakening and becoming a shallow system, it will be steered by the low-level flow on a general west to west-northwest track for the next several days until dissipation.
