Tropical Storm EARL Forecast Discussion Number 1

Issued at 1200 PM EDT TUE AUG 02 2016 000 WTNT45 KNHC 021557 TCDAT5 TROPICAL STORM EARL SPECIAL DISCUSSION NUMBER 1 NWS NATIONAL HURRICANE CENTER MIAMI FL AL052016 1200 PM EDT TUE AUG 02 2016 Data from an Air Force reconnaissance plane indicate that the strong wave we have been tracking for days has developed a closed circulation center with an estimated pressure of 1001 mb. On this basis, advisories on Tropical Storm Earl have been initiated. This is the fifth tropical storm of the 2016 hurricane season. The overall convective pattern was a little less organized this morning, but recent images indicate that an area of deep convection is forming near or over the center. The upper-level outflow is not well established yet in all quadrants due to some shear. Most of the global models show that the upper-level environment should become more favorable with less shear. The NHC forecast calls for some intensification, and Earl is expected to be near hurricane strength by the time the center approaches the Yucatan peninsula. Earl has been moving westward rapidly around 19 kt embedded within very strong easterly flow around the periphery of the Atlantic subtropical high. The ridge extends westward across the southern United States, and this pattern should maintain the cyclone on a general westward track across Belize and Yucatan during the next couple of days. After that time, a weakened Earl should move over the southern Bay of Campeche and southern Mexico. The cyclone should slow down during the next 12 to 24 hours since the steering currents are expected to be weaker. Most of the dynamical guidance agree on this scenario, and the NHC forecast very closely follows the multi-model consensus.
