NASA Satellite imagery has indicated that the low pressure area in the eastern Pacific Ocean that forecasters are watching for possible development is slow to grow.

Visible imagery from the Geostationary Operational Environmental Satellite, GOES-11 captured on July 30 at 1530 UTC (11:30 a.m. EDT) showed the low as a comma-shaped area of clouds off of the west Central American coast. GOES satellites are operated by NOAA. The NASA GOES Project, located at NASA’s Goddard Space Flight Center in Greenbelt, Md. creates imagery and animations using data from the GOES series of satellites.

The broad area of low pressure that forecasters are watching is centered about 500 miles south of the Gulf of Tehuantepec. The low continues to produce showers and thunderstorms as it moves westward and west-northwestward at around 10 mph. The National Hurricane Center expects that any further development of this low pressure area will be slow, and gives the low a 20 percent chance of becoming a tropical cyclone over the weekend.
