Environmental conditions are conducive for additional development, and a tropical depression is likely to form during the next day or so while the system moves west-northwestward at 10 to 15 mph, parallel to and just offshore of the coast of Mexico. This system could produce locally heavy rainfall along portions of the coast of southern Mexico during the next day or two. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...high...90 percent. * Formation chance through 5 days...high...90 percent. Another low pressure system located more than 900 miles west- southwest of the southern tip of the Baja California peninsula is producing limited shower and thunderstorms activity. Conditions have become less conducive for development and the chance of this system becoming a tropical cyclone is decreasing. The system is forecast to move little during the next couple of days. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...medium...40 percent. && High Seas Forecasts issued by the National Weather Service can be found under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at ocean.weather.gov/shtml/NFDHSFEPI.php $$ Forecaster Brown
