The circulation around Tropical Depression Celia weakened during the weekend. A few thunderstorms formed near the center of Celia, but most of the circulation consisted of bands of showers and lower clouds. An upper level ridge over southeastern Mexico produced easterly winds that blew across the top of Tropical Depression Celia. Those winds caused moderate vertical wind shear. The wind shear blew the tops off of many of the thunderstorms that started to develop in Tropical Depression Celia.
Tropical Depression Celia will move through an environment mostly unfavorable for intensification during the next 24 hours. Celia will move over water where the Sea Surface Temperatures are near 28˚C. However, the upper level ridge over southeastern Mexico will continue to cause moderate vertical wind shear. The wind shear will prevent intensification during the next day or so. Tropical Depression Celia will move into an area where the upper level winds are weaker early next week. That will cause the vertical wind shear to diminish. Tropical Depression Celia could strengthen when the shear diminishes.
Tropical Depression Celia will move south of a high pressure system over Mexico during the next 48 hours. The high pressure system will to steer Celia toward the west. On its anticipated track Tropical Depression Celia will move parallel to the south coast of Mexico.
