Rain drenches the country, and there is more on the way

Weather is delivering a one-two punch. Graphic: U.S. National Hurricane Center

The rain Monday afternoon and evening was courtesy of tropical wave No. 15, according to the Instituto Meteorológico Nacional. The instability generated storms that dropped nearly 3 inches of water on parts of the Central Valley.

The U.S. National Hurricane Center said that the wave was accompanied by a weak surface low pressure system near the coast of NIcaragua. The combination produced a large area of cloudiness and thunderstorms.

However, the center said it doubted that the system would become stronger as it moved slowly west northwest.

The bulk of the rain will fall on Nicaragua, Honduras and Belize, it said.

Yet another tropical wave is headed in the direction of Costa Rica. At midnight it was about 250 miles east of the Windward Islands and just north of the Venezuelan coast. Forecasters said they also doubted this would grow into a more serious storm.

Some of Monday’s heaviest rain seems to have fallen at the Universidad de la Paz in Ciudad Colón. An automatic weather station there measured 66.8 millimeters or about 2.63 inches. The rains began about 2 p.m.

Juan Santamaría airport measured 52 millimeters or about 2.04 inches. The biggest downpour, some 73.9 millimeters or 2.9 inches, fell on desolate Volcán Turrialba, according to the weather station there.

Meteorologists at the Instituto Meteorológico Nacional were concerned enough to issue a special bulletin at 7 p.m. The bulletin said rivers were rising on the Pacific coast as a result of rain in the vicinity of 50 millimeters. The weather service warned about the Río Caño in the south Pacific, the Río Parrita in the central Pacific and the Río Tenorio in the north Pacific.

The weather service emphasized the potential danger at vulnerable areas where slides can be provoked by wet soil. The bulletin warned of possible problems in Escazú, Santa Ana, Alajuelita and Desamparados.

Early today the Policía de Tránsito reported no slides or road blockages, but the full extent of the rain’s impact will not be known until later today.

The storm ended four days of cloudy but generally dry weather that made for a comfortable weekend.
