Romania: Heatwave forecast to continue across much of the country through at least Aug. 27

Forecast models indicate the ongoing heatwave will persist across much of Romania through at least Aug. 27. Maximum daily temperatures of 36-38 C (97-100 F) are forecast, with minimum nighttime temperatures of 19-23 C (66-73 F). The National Meteorological Administration has issued orange (middle level on a three-tier scale) heatwave and high-temperature warnings across western, southern, and eastern Romania Aug. 26. Yellow heatwave and high-temperature warnings are in place across the rest of the country Aug. 26-27. Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.

The extended period of oppressive heat and dry conditions may produce ideal circumstances for additional 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 some passengers being hospitalized for dehydration.

High temperatures may warp rail tracks and force passenger and freight trains to operate at reduced speeds. 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 regional airports, 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.
