From NASA Goddard- Atlantic hurricane season sticks to the calendar: System 93L
NOTE: I’ve posted the most current image below, the system has already crossed the Florida peninsula and is now in the Gulf of Mexico – Anthony
Hurricane season starts today, June 1, in the Atlantic Ocean and the tropics are paying attention to the calendar. The GOES-13 satellite has been capturing images of a low pressure area that formed off the North Carolina coast yesterday and is now located off of the northeastern Florida coast.
The low pressure area, also known as System 93L appears somewhat elongated, almost rounded area of clouds on the satellite imagery today, stretching from southwest to northeast. The Geostationary Operational Environmental Satellite called GOES-13 has been capturing imagery of the low since it formed. The visible image from June 1 at 1445 UTC (10:45 a.m. EDT) has some shadows in the middle of the storm, which indicate that there are some towering, strong thunderstorms near the circulation center that are casting shadows onto the lower thunderstorms.
NASA’s GOES Project, located at NASA’s Goddard Space Flight Center, Greenbelt, Md. creates imagery and animations of GOES satellite data. The GOES series of satellites are operated by the National Oceanic and Atmospheric Administration.

At 8 a.m. EDT, the center of the low was about 200 miles east of Jacksonville, Florida and was moving west-southwest near 20 mph. It is forecast to move over northern Florida later today toward the Florida Panhandle. It has a medium chance of becoming the Atlantic hurricane season’s first tropical depression in the next 24 hours.
The low does mean some scattered strong thunderstorms are in the forecast for northeastern Florida and isolated thunderstorms in southeastern Georgia today. The National Weather Service noted that some of the thunderstorms could contain wind gusts to 50 mph, small hail, frequent cloud to ground lightning and heavy rainfall.
In addition to the threat of severe thunderstorms, the low is also creating rip currents and building swells along the eastern Florida beaches. For updates, visit NASA’s Hurricane Web Page at: www.nasa.gov/hurricane
If the low does intensify into a tropical storm it would receive the name Arlene. However, it must first reach tropical depression status. Even if it doesn’t become a depression it still means severe weather for northeastern Florida and southeastern Georgia today.
