Panama: Adverse weather forecast across much of the country through at least March 27

Adverse weather is forecast across most of Panama through at least March 27. Panama's Hydrometeorological Service has issued a weather advisory warning of light to moderate rainfall and thunderstorms the afternoons of March 26-27. Maximum rainfall accumulations of 0.1-1.5 cm (0.04-0.6 inches) over the Caribbean Sea side, 0.5-2.5 cm (0.2-1 inches) over the Pacific Ocean side, and over 3 cm (1.2 inches) over mountainous areas are forecast. The heaviest rainfall is forecast over western and central Panama. Heavy downpours could result in floods and flash floods in urban or low-lying areas, as well as landslides on unstable slopes. Officials could update and possibly extend the coverage of weather alerts over the coming days.

Sustained heavy rainfall could trigger flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed stormwater drainage systems. Sites downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where the soil has become saturated by heavy rainfall. Disruptions to electricity and telecommunications services are possible where significant flooding, landslides, or strong winds impact utility networks.

Floodwaters and debris flows could render some bridges, rail networks, or roadways impassable, impacting overland travel around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters.

Severe weather could also trigger intermittent flight delays and cancellations at airports in the region, including Tocumen International Airport (PTY), though these are unlikely to be severe or prolonged. Authorities may temporarily suspend port operations if strong winds trigger hazardous sea conditions, impacting freight and passenger maritime traffic. Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas that see heavy rainfall and potential track inundation. Localized business disruptions may occur in low-lying areas.
