Another low-pressure area has sprung up like a mushroom in the southern Caribbean, and weather forecasters say this will influence conditions later today and over the weekend.
Meanwhile, there still are predictions for high winds generated by a high-pressure area over the Yucatan peninsula. The Instituto Meteorológico Nacional said that the winds also intensify rain in the Caribbean coast and the northern zone. In the afternoon and evening the Pacific and the Valley Central will see rain, it said.
The U.S. National Hurricane Center said that the broad low-pressure area is about 150 miles east southeast of the Honduras-Nicaragua border. Further development of the system is expected to be slow,in part because the air is dry. However, conditions are expected to be more conducive for development in a few days as it drifts southward.
There is another patch of disturbed air heading west in the mid-Atlantic. Forecasters have their eye on this, too.
The Consejo Nacional de Vialidad said that officials were forced to close a 55-kilometer section of Ruta 239 between Santa Marta and Salitrales Thursday afternoon.
The Interamericana Sur was still closed at Casa Mata. The Consejo reported advances in trying to reopen the stretch. Much of the roadbed collapsed into an adjacent ravine. The Consejo said that utility poles were being moved and workers were excavating the shoulder opposite the collapsed part to create a traffic lane. Even when the job is done, only one lane will be available, said officials
Pipelines also have to be rebuilt in new locations, and gutters and other systems for carrying off rain water have to be built, they said.
