1. INVEST 99L continue to show some consolidation of the showers and storms.  Once the convection (thunderstorms) clusters together we can see further organization into a tropical cyclone into the coming week...RTW

2.  INVEST 90L This system has been trying to organize during the day. I do believe that as this system tracks further west it may develop into a depression or tropical storm...RTW

RTW:  Ralph's Tropical Weather

1. INVEST 99L Showers and storm seems to be consolidating and seem more concentrated.  So far most of the models in the 12z run don't show much organization with 99L so will have to continue watching as it tracks west-northwest. Model track are flip flopping some are tracking north of the islands in previous run and now they are tracking south into the Caribbean or over the greater Antilles.  I will continue to monitor into next week...RTW

2.  INVEST 90L Thunderstorms are accumulated more now that the wave southern axis is not interacting with Colombia.  This system now has a 30% chance for development within 48 hrs. and a 50% chance within 5-days...RTW

RTW:  Ralph's Tropical Weather

1. INVEST 99L Not much going on with this system at this time.  Environmental conditions are forecast to become more favorable as this system tracks west to a west-northwest in the coming week. The atmosphere to the north of this system is still setup for a track mainly to the west northwest and if this persist it could be a problem for the U.S. east coast in the coming weeks...RTW

2.  INVEST 90L is gradually gaining organization as it tracks further west toward the  Yucatan and into the BOC (Bay of Campeche) in the coming week...RTW
