Turkey: Thunderstorms forecast across the southwestern region through at least Nov. 2 /update 1
Thunderstorms forecast across southwestern Turkey through at least Nov. 2. Disruptions possible.
Event
Rounds of thunderstorms are forecast to occur across the southwestern region through at least Nov. 2. As of early Nov. 2, authorities have issued orange (middle level on a three-tier scale) warnings for thunderstorms across Adana, Antalya, and Mersin provinces. Officials could update and possibly extend the coverage of the weather alerts over the coming days.
Hazardous Conditions
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 cannot be discounted in hilly or mountainous areas, especially where the soil has become saturated by heavy rainfall.
Authorities could issue mandatory evacuation orders for flood-prone communities over the coming days. The adverse weather conditions could cause power outages throughout the affected area through at least Nov. 2.
Transport
The severe weather will likely contribute to transport disruptions throughout the region. Traffic and commercial trucking delays might occur along regional highways. Strong winds might pose a hazard to high-profile vehicles. Floodwaters and debris flows may render some bridges, rail networks, 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 regional airports. Authorities may temporarily suspend port operations along the Aegean and Mediterranean Seas 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 likely in areas that see heavy rainfall and potential track inundation. Flooding will further exacerbate transportation disruptions already occurring in areas under restriction due to COVID-19 activity.
Disruptions triggered by inclement weather and resultant hazards, such as flooding, could persist well after conditions have improved. It could take days before any floodwaters recede and/or officials clear debris. If there is severe damage to infrastructure, repair or reconstruction efforts may result in residual disruptions.
Advice
Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments prior to travel. Make allowances for localized travel delays, as well as potential supply chain disruptions, where flooding has been forecast. Do not drive on flooded roads. Review contingency plans and be prepared to move quickly to shelter if tornado warnings are issued. Charge battery-powered devices in the case of prolonged electricity outages.
