Hyderabad, Sep 8 (TOI): Massive downpour in areas across Telangana and north coastal Andhra Pradesh districts on Sunday rendered hundreds of people marooned in several villages as roads and communication links remained cut off even as many rivers and streams flowing at dangerous levels prompted authorities to gear up for emergency evacuation.

Danger warning signal No. 1 was issued in Bhadrachalam town as the water level in the Godavari crossed 45 feet. The danger warning here is issued if the water level crosses 42 feet, officials said.

In north coastal Andhra, the river Vamsadhara is in spate with heavy flood discharge forcing officials to issue danger warning signal No. 2. With the outflow of the Vamsadhara reaching up to 1.06 lakh cusecs at Gotta barrage in Srikakulam district on Sunday, district collector Gaurav Uppal was informed that as many as 124 villages falling under 11 mandals along the rivers would be affected if flood situation further continued. The irrigation officials expect the outflow to increase up by another 10,000 cusecs by Monday due to the continuous rains in the catchment areas in Odisha.

Similarly, the Godavari has been rising menacingly near Bhadrachalam. "Water level has been rising by one foot every hour, with the catchment area reporting as high as 12 cm of rainfall," said a government official. "The situation in other places is also grim," he said.

The incessant heavy rains under the influence of the southwest monsoon have marooned several Godavari island hamlets and inundated thousands of acres of agricultural fields.

Coal production was also badly hit in the open cast mines of Singareni Collieries after flood waters entered the quarries. Officials said water pumping motors were submerged at the Medipalli open cast mines and according to modest estimates, about 40,000 tonnes of coal production was hit in open cast mines 1 and 2.

Senior officials in AP and Telangana were instructed to closely monitor the flood situation and evacuate people whenever needed at a short notice.

About 70 villages in Adilabad and Khammam districts in Telangana were cut off with flood water inundating roads, causeways and bridges.

The flood discharge from the Dhowleswaram barrage across the river Godavari near Rajahmundry on Sunday was 4.21 lakh cusecs. Several tributaries of the river are also in spate forcing authorities to issue alert warning to people living in low-lying areas in Telangana and Andhra Pradesh. The Srisailam and Nagarjunasagar dams continued to receive heavy inflows due to rains in the catchment area. Water level in the Srisailam dam has reached its full capacity, while the Nagarjunasagar dam is half full, officials said. The Musi also received heavy inflows into its reservoirs in Hyderabad, thanks to heavy rains in its catchment in Tandur and Vikarabad areas.

In Adilabad district, officials have already shifted people from a few low-lying villages as major rivers in the district, Pranahita and Penganga, are in spate.

Power supply was hit as rainwater uprooted electric poles in many places, while authorities switched off power as a precautionary measure.

The meteorological department on Sunday said heavy to very heavy rainfall was on the cards across Telangana and AP on Monday too.
