As of the 11AM EDT advisory from the National Hurricane Center, Tropical Storm Alberto was still drifting along towards the southwest with 45 MPH winds. A Tropical Storm Watch is still in effect for parts of the South Carolina coast, but the odds of these areas experiencing tropical storm conditions are lowering with each tick of the storm away from SC.
Alberto is currently moving towards the southwest, but an approaching midlevel trough will force the storm to turn right back around and start moving northeast. A low pressure system is currently sitting about 50 miles east of Ocean City, MD right now, which is effectively serving to block Tropical Storm Alberto from racing northeastward out to sea. This low is forecast to move inland over the next few days, which will open up a large ridge over the Atlantic and allow Alberto to move progressively faster out to sea.
