Islamabad, Pakistan (CNN) -- Some 14 million people have been affected by the torrential rains and flooding that have left more than a thousand dead in Pakistan, a spokesman for the national disaster authority told CNN Tuesday.
While 1,245 people have been confirmed killed, officials believe the number of dead may reach 1,500, said spokesman Ahmed Kamal.
He said 1,334 people have been injured and 337,282 people have been rescued so far. More than 302,000 houses have been damaged, Kamal said, but that number may more than double by the time the disaster is over.
Pakistan's Meteorological Department said more heavy rains were in store in the next few days, threatening to deepen the worst natural disaster the nation has experienced in recent history. The monsoon season is still only halfway over.
The flooding, which started in the northwest, threatened places as far south as the port city of Karachi.
Nineteen people died across the country between Sunday and Monday nights, Kamal said.
The weather in the northwest province of Khyber Pakhtunkhwa did improve slightly Tuesday, which allowed some 23 helicopters to take off for relief and rescue operations, according to a military spokesperson who did not want to be named. CNN
