Sri Lanka: Heatwave to continue nationwide through at least April 1
Heatwave to continue in Sri Lanka through at least April 1. Transport, utility, and power disruptions possible.
Event
Forecast models indicate that a heatwave will persist nationwide through at least April 1. The Sri Lankan Department of Meteorology has issued an amber caution (second-lowest level on a four-tier scale) advisory for Western, Northern, North-Central, and North-Western provinces as well as Galle and Matara districts due to the high heat index (the temperature felt on the human body due to relative humidity and maximum temperatures) forecast. Authorities could downgrade or expand warnings as the heatwave develops.
Authorities have advised residents to limit strenuous outdoor activities, find shade, and stay hydrated. Residents should lightweight and white or light-colored clothing to minimize the possibility of heat stress.
Hazardous Conditions
The extended period of oppressive heat and dry conditions may produce ideal circumstances for wildfire growth throughout the region. Heatwaves also pose a threat to vulnerable groups - such as the elderly, children, pregnant women, and those with respiratory illnesses - due to the increased possibility of heat stroke or heat exhaustion during prolonged exposure to high temperatures. These health risks could also extend to relatively healthy individuals during significant heatwave events. In addition to significantly impacting athletes and those who work outdoors, high temperatures can cause problems for people using mass transit. The lack of air conditioning and cramped vehicles during rush hour may lead to the hospitalization of some passengers due to dehydration.
Transport and Utilities
Very high temperatures may warp rail tracks and force passenger and freight trains to operate at reduced speed. Road surface damage is also possible, and overheated vehicles may worsen traffic problems in urban areas where congestion is already a problem. Commercial trucking disruptions might occur as very high temperatures put more stress on engines, making tire blowouts more common. Major flight disruptions are unlikely at airports in the region, but general aviation disruptions are possible, and some airfreight carriers could reduce cargo loads. High temperatures could lead to an increased demand for electricity, which might trigger localized brownouts or blackouts, exacerbating hazardous conditions when air conditioning is no longer possible.
Advice
Monitor local media for weather updates and related advisories. During heat waves, remain indoors in air conditioning when possible. If outdoor activities are necessary, frequently rest in shaded areas; avoid activity during the hottest times of the day. Stay well hydrated by drinking plenty of fluids. Avoid alcoholic beverages, which are dehydrating - drink bottled water or water that has been boiled. Wear loose-fitting, light-colored clothing. Cotton fabrics are more cooling than synthetics. Promptly seek medical attention if signs of heat exhaustion or heat stroke develop. Charge battery-powered devices in case prolonged electricity outages occur.
