NEW ORLEANS (AP) - Weather forecasters are reducing the likelihood that a tropical weather system will develop from a remnant of Hurricane Isaac that drifted south and into the Gulf of Mexico.
    
The National Weather Service on Friday reduced the probability of development to 20 percent. It had been 40 percent on Thursday.
    
The area of low pressure was described by forecasters as a small part of the Isaac circulation system that dissipated over Ohio. Earlier this week, a weather service meteorologist dubbed it the "spawn of Isaac."
    
Louisiana emergency officials have been getting daily briefings on the low pressure system, which had moved farther south overnight and was drifting eastward Friday morning. With a cold front approaching, the system was forecast to move toward the Florida panhandle over the weekend.
