Within a day, the well-marked low pressure area in the Bay of Bengal underwent a series of changes and intensified finally into a cyclonic storm named by weathermen as “Mahasen” and lay 1,300 km southeast of Chennai and 350 km southwest of Car Nicobar islands on Saturday.

Mahasen was likely to further intensify into a severe cyclonic storm on Sunday and move northwest wards before turning towards northeast to approach the coast of Bangladesh and Myanmar.

Indications were available for the time being from the mid-summer weather phenomenon that it would have only peripheral impact on Andhra Pradesh and Tamil Nadu. At most, the coastal areas of these States may get some rains when the cyclonic storm moves on, an official in State Met Office said.

Even as a wary government kept a watch on the situation relating to the cyclonic storm, Andhra Pradesh presented two contrasting pictures for the day, with heat wave conditions continuing over Coastal Andhra and Telangana regions while some places received rains. Bapatla recorded a rainfall of 5 cm, Udsyagiri 2 cm and Seetharampuram and Mangalarigi 1 cm each.

Scorching heat enveloped several places in Coastal Andhra and Telangana. Rentachintala and Nandigama, both in Coastal Andhra, recorded the State’s highest temperature for the day at 45 degrees Celsius. The temperatures at over a dozen other places hovered above 42 degrees C.

A warning about continuance of the heat wave conditions has been issued to the districts of Nellore, Prakasam, Guntur, Krishna, Karimnagar, Nizamabad, Medak, Warangal and Adilabad.
