Panama: Adverse weather forecast nationwide through at least Dec. 2
Thunderstorms and heavy rainfall forecast across Panama through at least Dec. 2. Flooding and disruptions possible.
Event
Adverse weather is forecast across most of Panama through at least Dec. 2. Panama's Hydrometeorological Service has issued a warning notice advising for rainfall and thunderstorms across the country through Nov. 29 due to unstable conditions triggered by areas of low pressure. Daily rainfall accumulations of 5-10 cm (2-4 inches) are forecast over parts of southern Veaguas Province and the Azuero peninsula Nov. 28, as well as totals of 2.5-5 cm (1-2 inches) likely across much of the rest of the country. Rainfall totals of 3-6 cm (1.2-2.4 inches) are expected over parts of Colce, Herrera, Los Santos, Panama Oeste, and southern Veraguas provinces Nov. 29, as well as 1.5-3.5 cm (0.6-1.4 inches) across much of the rest of the country. Storms may be accompanied by strong wind gusts, lightning, and possible hail. Further showers and storms are forecast across Panama through at least Dec. 2. The heavy rain could result in floods and flash floods in urban or low-lying areas. Landslides are also possible. Officials could update and possibly extend the coverage of weather alerts over the coming days.
Hazardous Conditions
Sustained heavy rainfall occur 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 located 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.
Transport
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.
Advice
Monitor local media for updated emergency and weather information. Seek updated information on weather and road conditions before driving or routing shipments through areas where severe weather is forecast. Plan accordingly for potential delivery delays if routing shipments by truck through the affected area. Do not attempt to drive through flooded areas. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
