Low Pressure System Approaches Southeast U.S.

A small low pressure system was approaching the Southeast U.S. on Friday morning.  The low pressure system was officially designated as Invest 92L by the U.S. National Hurricane Center.  At 11:00 a.m. EDT on Friday the center of the low pressure system was located at latitude 30.4°N and longitude 79.5°W which put it about 135 miles (215 km) east of Jacksonville, Florida.  The low pressure system was moving toward the west-northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1014 mb.

The low pressure system approaching the Southeast U.S. was officially designated as Invest 92L, but it exhibited many of the characteristics of a tropical depression.  Thunderstorms were occurring near the center of the low pressure system.  Thunderstorms were also occurring in bands in the southern half of the circulation around Invest 92L.  Bands in the northern half of the circulation consisted primarily of showers and lower clouds, although there were also a few thunderstorms.  Storms near the center of circulation generated upper level divergence that pumped mass away to the southwest of the low pressure system.

The low pressure system approaching the Southeast U.S. will move through an environment somewhat favorable for intensification during the next few hours.  The low pressure system will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the southeastern part of an upper level ridge that stretches from Texas to Maine.  The upper level ridge will produce northeasterly winds that will blow toward the top of the low pressure system.  The wind shear will inhibit intensification.  The low pressure system could strengthen a little, if the upper level winds do not get stronger.

The low pressure system will move around the southern side of a high pressure system that is over the western Atlantic Ocean and eastern U.S.  The high pressure system will steer Invest 92L toward the west-northwest during the next 24 hours.  On its anticipated track, the low pressure system will make landfall on the coast of Georgia later on Friday.

The low pressure system designated as Invest 92L will bring gusty winds and locally heavy rain to parts of northeastern Florida and eastern Georgia.  It will also generate waves and rip currents along the coast.  The waves could cause some minor coastal erosion.
