Tropical Storm Earl Has Formed… Tuesday Update 11am #alwx @wvua23


Good Tuesday morning! At 11am, it’s official… Tropical Storm Earl has formed in the northern Caribbean. With a strong ridge over the central US, Earl will remain well to our south… Here’s the discussion from the National Hurricane Center on Earl:

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.
