Tropical Storm Lidia Weakens, Still Raining on Baja California

Tropical Storm Lidia has weakened but it is producing rain over Baja California.  At 2:00 p.m. EDT on Saturday the center of Tropical Storm Lidia was located at latitude 28.3°N and longitude 114.6°W which put it about 40 miles (65 km) northeast of Punta Eugenia, Mexico.  Lidia was moving toward the northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 999 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Punta Abreojos to San Jose de Las Palomas, from Mulege to Isla San Luis and from Guaymas to Puerto Libertad, Mexico.

Tropical Storm Lidia weakened during the past 24 hours as it slowly moved northwest over Baja California.  There are some indications that the upper portion of the circulation may have decoupled from the lower half of Tropical Storm Lidia.  The upper portion of the circulation appears to be over the Gulf of California.  There are stronger thunderstorms over the Gulf of California because the Sea Surface Temperature is near 32°C in that body of water.  Those thunderstorms are producing heavy rain over parts of the eastern side of Baja California and the western part of Mexico adjacent to the Gulf of California.  The lower level center appears to be located northeast of Punta Eugenia over the Pacific Ocean just west of Baja California.  There are showers and thunderstorms near the low level center and they are dropping heavy rain in that area.  The potential for flash floods still exists in the areas where heavy rain is falling.

The low level center of Tropical Storm Lidia is forecast to continue to move toward the northwest.  Lidia will continue to weaken because the low level center is moving over water where the Sea Surface Temperature is near 23°C.  It will take several more days for the low level center to spin down and it could still produce locally heavy rain over the northern part of Baja California during that time.  The upper level portion of the circulation will likely be absorbed by the larger scale environmental flow in those levels.  Some clouds and moisture in the upper levels could flow over the southwestern U.S.
