Hurricane Summary POSTED: September 2, 2010 5:31 p.m. Tropical Development Increasingly Likely An area of low pressure about 150-200 miles west of Manzanillo, Mexico, Thursday continues to drift slowly off to the west-northwest at close to 5 mph. The low pressure continues to show periodic flare-ups of increased thunderstorm activity, but these have not yet consistently organized around the center of circulation. As soon as the thunderstorm pattern can become more consistent and wrap around the center of circulation, the low pressure area will likely be upgraded to a depression or perhaps even a tropical storm. The low pressure center is in an area with warm waters and weak upper-level winds, so development seems likely within the next 24-36 hours. Computer forecasts show this feature tracking west-northwest slowly under the influence of an upper-level ridge over northwestern Mexico. This should keep the system on a course away from the Mexican coast. Another disturbance over the Isthmus of Tehuantepec shows some sign of development. There are no other areas of interest in the East Pacific basin at this point in time. By AccuWeather Expert Senior Meteorologist Bob Smerbeck
