Thunderstorms threaten to hinder efforts to free the 150 people feared trapped after a flyover collapsed in Kolkata, India, on Thursday.
At least 14 people were killed when the flyover under construction collapsed onto a street with moving traffic below near Kolkata's Girish Park, Reuters reported.
No rain or strong winds were reported at Kolkata's international airport Thursday morning and early afternoon. Dry weather, instead, prevailed as temperatures climbed to 36.1 degrees Celsius (97 degrees Fahrenheit).
"There was some heavy rain in the area on Wednesday," AccuWeather Senior Meteorologist Jason Nicholls said.
"There will be showers and thunderstorms around Thursday afternoon and evening and again Friday afternoon."
Such unsettled weather threatens to hinder or suspend rescue efforts, especially with the prospect of lightning.
Reuters reports that "access for heavy lifting equipment [is] restricted by the proximity of buildings on either side of the flyover and heavy traffic."
Construction on the flyover has been ongoing since 2009 with several deadlines for completion missed.
