Bahamas: Adverse weather forecast across the country through at least Nov. 17

Severe weather is forecast across much of the Bahamas through at least Nov. 17. A low-pressure system is moving over the country as of early Nov. 17, and a second system is expected to arrive Nov. 18 before exiting the Bahamas Nov. 19. A combination of heavy rainfall and strong winds are expected in central and northern regions during the passing of the weather systems, with the most severe weather likely in the extreme northwest; rainfall totals of 5-10 cm (2-4 inches) with localized maximums of up to 15 cm (6 inches) and winds gusting up to 61 kph (38 mph) are forecast. Strong winds will likely generate rough seas, and smallcraft operators and mariners have been advised to remain in port.

As of early Nov. 15, the Bahamas Department of Meteorology has issued excessive rainfall and severe weather watches for extreme northwest and northwest Bahamas and gale watches for extreme northwest, northwest, and central Bahamas. Officials could update and 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 or a lack of 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 heavy rain has saturated the soil. Disruptions to electricity and telecommunications services may occur where significant winds, flooding, or landslides impact utility networks.

Floodwaters and debris flows may render some bridges or roadways impassable, impacting overland travel in and 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 flight delays and cancellations at airports. Authorities may temporarily suspend port operations or close beach fronts if strong winds trigger hazardous sea conditions.

Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities and some employees' inability to reach work sites.
