Thursday, May 30
There is tropical activity in the Atlantic Basin.
In the East Pacific Ocean, Tropical Depression Barbara is currently located40mi NW of Coatzacoalcos, Mexico at 18.5N 95.0W. Max sustained winds are 30.mph with higher gusts. Min Central Pressure 1005mb (29.68"). Barbara is moving NW (310) at 3mph.
Finding the Low-level center of Barbara has been a challenge. The center of rotation as visible in Satellite Imagery is not consistent with surface observations. This means that the mountainous terrain has taken its toll on this, now, Tropical Depression.
When dealing with terrain that is jagged with mountains, you see a lot of shear. This is bad for the development of tropical systems. This Shear problem is also leading toward doubt that a well-defined surface center even exists.
This storm will remain a depression until more satellite and radar analysis is complete. Nevertheless, there has been a lot of degeneration with this system and it will not be long-lived from here on out.
T.D. Barbara will continue to move to the WNW as it breaks down only drawing limited Gulf Moisture from its Northern side.
Most guidance shows that this storm will not move too far into the GoM (Gulf of Mexico) before fizzling out
Either way, the threat that remains for Mexico is heavy rainfall coupled with some flooding for the next several days.
Elsewhere, tropical development is not expected during the next 48 hours.
