canal

Aug. 21 (UPI) — The Panama government blamed low rainfall caused by El Niño for a decision to cut the number of vessels permitted to transit the 51-mile-long Panama Canal by more than 11%, despite being in the middle of the wet season.

Shipping lines were notified by the Panama Canal Authority on Thursday that as of Sept. 15, it was slashing the number of daily ship movements through the canal from 36 to 32 to ensure there was no disruption to traffic and to conserve water for human consumption.

The authority said the step was necessary “to support the long-term sustainability of transit operations,” even though it had already implemented other water-saving measures and the rainy season had finally arrived.

With the sea-warning El Niño weather cycle expected to be one of the most intense on record, Britain’s Met Office said Central America, along with tropical South America and countries in the western Pacific, was at significant risk of low rainfall in this year’s wet season.

With vessels already lining up to transit the canal, in some cases for weeks, fears were growing of a knock on impact from the delays and extra costs on goods prices, including fuel and medicine.

One container ship reportedly paid $4 million to jump to the front of the line.

San Francisco-based freight-forwarding firm Flexport, which had 30 containers on the ship, told CNN that the delays at the Pacific end were the longest in three months, when there was significant backlog due to a surge in demand from maritime traffic displaced by the closure of the Strait of Hormuz.

“The ripple effects are significant through supply chains and all the way to consumer prices at stores,” said Benjamin Gedan, senior fellow and director of the Latin American program at the Stimson Center in Washington.

The canal relies on fresh water from Lake Gatun to feed 12 sets of locks that use water compartments to move vessels up or down as they navigate the topography of the Panama Isthmus.

Extreme drought during El Niños in 2023 and 2024, forced Panama to impose deep cuts in the number of ships transiting daily — 24 compared with 36 in normal times — after water levels in Lake Gatun retreated to historic lows.

The El Nino weather phenomenon is expected to increase the likelihood of drought and excess heat across the region.

The Panama Canal is expected to limit traffic starting in early September, as it prepares for lower water levels due to the El Nino weather phenomenon.

On Thursday, the Panama Canal Authority, the body that oversees the waterway, announced that daily transit caps would be set to address concerns about the drier weather conditions ahead.

Under the new measures, 34 vessels will be permitted to sail through the canal as of September 4. A further reduction will start on September 15, when the limit will be 32 ships.

The travel restrictions are a reversal for the Panama Canal Authority. Officials told the news service Reuters in May that they had no plans to limit crossings this year, citing water conservation measures imposed last year.

The canal, which handles about 5 percent of global maritime trade, usually has capacity to accommodate about 40 vessels per day.  Since June, it has seen a daily average of 35 transits.

Any significant decrease in travel through the canal is likely to translate into slower international shipping for industries that rely on the waterway. That, in turn, could increase costs.

A severe drought in 2023, for instance, cut traffic through the Panama Canal by roughly 36 percent, leading to disruptions in global supply chains.

The declining water levels that year were also attributed to El Nino, as well as climate change accelerated by human activities.

El Nino is a naturally occurring weather phenomenon that takes place every two to seven years, when the eastern tropical Pacific Ocean is warmer than usual.

The resulting weather patterns can have an impact across the region and even globally, putting some areas at risk of excessive heat and drought, while others suffer from flooding

Scientists expect a particularly strong El Nino in the coming months, potentially among the strongest on record. That could lead to an increase in cases of extreme weather events.

Panama Canal authorities have previously imposed vessel limits in order to conserve water.

The canal relies on a lock system that lifts and lowers vessels as they travel from the Pacific Ocean to the Caribbean Sea, and vice versa.

But the canal is fed, in part, by freshwater from nearby lakes and reservoirs, most notably Gatun Lake.

Panamanians rely on that lake as well to supply drinking water to nearby cities, including the capital Panama City, putting additional strain on the waterway during times of drought.

There are few pastimes more relaxing than messing about on the river.
