Tropical Storm Emily formed last night over the eastern Gulf of Mexico. An area of low pressure developed thunderstorm activity which managed to consolidate and organize as it approached the central gulf coast of Florida overnight. Meteorologists began to notice the increasing organization of the system on local radar and at 6 am EDT this morning, the National Hurricane Center in Miami declared the system “Emily”.
As an upper atmospheric trough of low pressure digs southeastward from the upper-Midwest over the next 2-3 days, this is expected to steer Emily northeastward. It will move out of Florida by overnight tonight/early Tue and head off into the open waters of the Atlantic well-offshore the East Coast. Land interaction today will weaken it but it may regain some strength over the waters of the Gulf Stream mid-week.
Atlantic tropical cyclone statistics thus far this season: 5 named storms, 0 hurricanes, 0 major hurricanes. On July 31st, on average the Atlantic is expected (based on 1966-2009 data) to have observed only 1 named storm, 0 hurricanes, 0 major hurricanes (on Aug 1st, the average named storms increases to 2). As we go deeper into the month of August expect the hurricane numbers to go up thanks to favorable below average wind shear and above normal oceanic heat content currently in existence in the Main Development Region (MDR) of the Tropical Atlantic.
This area is largely turned off in earlier months but ramps ups later in the season as tropical waves develop from the tropics of West Africa and moves south and west of the Cape Verde Islands. So the Atlantic still has a lot left in the tank as far as heat energy to release.
