Heavy rains and landslides in Costa Rica

Despite the grim forecasts back in early October that a ridiculous amount of rainfall was going to drown Costa Rica for the rest of 2010, most of October was downright beautiful! Clear, sunny mornings with acceptable rain in the afternoons seemed to have trumped the weather people. This past Tuesday, however, the rains came back with a  vengeance and the results were tragic as Hurricane Thomas in the Caribbean and a low pressure system in the Pacific combined forces to dump all of October’s expected precipitation in just 48 hours.

It started on Tuesday, didn’t stop until Thursday, rained again for all of Thursday night and appears to have finally let up as I write this on Friday morning. As I was scheduled to guide in the Carara area on Wednesday and Thursday, I witnessed some of this deluge in my attempt to reach the coast on early Wednesday morning. As it had rained for the entire night and was still pouring down at 5 a.m., I left the house wondering if I should just stay home because such heavy rains typically result in landslides.

I figured I would at least drive past Atenas to where I could see into the Pacific Lowlands from an overlook. It was raining hard in the Central Valley but I thought, “Who knows? Maybe the sun would be shining on the coast”. My anxiety grew, however, as I drove on the highway and noticed massive puddles forming on the sides of the road and drainage ditches overflowing with torrents of rushing, clay colored water. At times, I could barely see out the windshield but decided to continue on to Atenas because the rain was a bit lighter once I took the exit to that quaint town at the edge of Central Valley.

As I approached Atenas, I saw a line of stopped cars straight ahead and as I had feared, yes, there was a small landslide blocking the road in both directions. To avoid possibly being stranded somewhere just shy of Atenas, I quickly turned around and drove back through the driving rain to home in Santa Barbara de Heredia. And a good thing too because as it turned out, there were bigger landslides further down the road that I was taking to get to the lowlands. There were also landslides that closed other roads, bridges were washed out, roads near Manuel Antonio were literally destroyed, and worst of all, twenty people were killed and more had their homes destroyed by a mudslide in San Antonio de Escazu.

Although few areas on the Caribbean Slope have been affected, the landslides have left the country in a state of emergency and mourning. Dozens of Ticos have lost their homes in Parrita, Escazu, and Aserri and thousands are without water, electricity, or cell phone use. Visitors to the country over the next two or three weeks could run into problems if traveling to such areas as:

• Manuel Antonio- Damage to roads and flooding in Parrita.
• Dominical- No access at the moment.
• Cerro de la Muerte and the Dota Valley- Landslides have shut down the highway over the mountain.
• Braulio Carrillo- Landslides have closed the highway.
• Southwestern Costa Rica including San Vito and the Osa Peninsula- At the moment, only accessible by air.
• Driving from the Pacific Coast to San Jose or vice versa- Landslides and road damage on all routes.

I suspect that most problems will be fixed by December (as long as we aren’t bombarded with similar amounts of rain in a short span of time), so I doubt that visitors to Costa Rica during the high and dry season will run into too many problems. On a side note, I am scheduled to guide at Irazu tomorrow. No issues have been reported from that area and the rain should stop by today so hopefully it will be sunshine and quetzals for tomorrow morning!
