Tropical Weather Update for Friday, July 3 2009

The upper level environment throughout the Tropical Atlantic is becoming more favorable for development this morning.  An upper low is slowly moving east through the western Caribbean this morning, touching off scattered showers and thunderstorms.  The upper low will continue to move to the east towards the Yucatan Peninsula by this evening.  No development is expected with this upper low.  The rest of the Caribbean is generally quiet due to the shear from the upper level low.  However, a weak wave entering the eastern Caribbean is showing some signs of life and may have to monitored in the next few days.  Any development will be slow however.  The rest of the tropical Atlantic is quiet as no other disturbance has shown much sign of development despite a much more favorable environment for development.  Finally, an upper low over the central Atlantic is starting to produce a weak surface feature.  There is a slight chance that this disturbance becomes a warm core or tropical system in the next few days.  However, the potential for this is relatively small.
