Why is the return of El Niño threatening Panama Canal operations?

El Niño weakens the winds that bring rain to Panama, reducing rainfall that feeds the canal’s two key reservoirs—Gatún and Alajuela lakes—on which the lock system depends for fresh water; low reservoir levels force the Panama Canal Authority to cut daily transit slots to conserve water, directly disrupting global shipping.

What specific operational changes has the Panama Canal Authority announced in response to worsening drought conditions?

The Panama Canal Authority will cap daily transits at 34 vessels starting September 4 and reduce it further to 32 vessels as of September 15, echoing the severe restrictions seen during the 2023–24 drought when daily transits fell as low as 22 ships.
