Sunday's deep depression progressively churned to the status of a cyclone with a name by late into the night and crossed the Andhra Pradesh coast by Monday noon.

The first of the season, Tropical Cyclone Ogni did not manage to foray much inland after crossing, said Dr K.J. Ramesh of the Department of Science and Technology.

`Half over water, half over land' is how he chose to put the scenario as prevailing on Monday evening.

Domineering still

He attributed this to the domineering eastward-bound upper westerly trough, which would not allow Ogni to venture much into the north-northwest.

The system has weakened into depression on crossing over, the IMD said.

It was expected to linger and play out along the coast mostly in a north-northeast direction in line with the guidance from the westerly trough.

The rain bands from the system could reach up to the Orissa coast, Dr Ramesh said.

Fails to register

The birth of the Cyclone Ogni in the Bay of Bengal does not seem to have registered with any of the international weather models surveyed.

Normally, a named cyclone gets prominently featured in all models, with separate guidance for expected course taken.

Except for IMD, no major model took cognisance of Ogni simply because the cyclogenesis occurred too far inside India's territorial waters and very close to the coast.

Only those rustling up required speed and intensity while parading the international waters are likely to get promptly noticed.

An India Meteorological Department update said Ogni crossed the Andhra Pradesh coast between Ongole and Bapatla around 1 p.m. on Monday.

It further weakened into a depression by 2.30 p.m. with its centre at about 25 km southwest of Bapatla. The system is likely to move in a north-northwesterly direction and weaken further. Under its influence, fairly widespread rainfall with heavy to very heavy falls is likely over a few places in Prakasham, Guntur, Krishna, West and East Godavari districts and adjoining Khammam and Nalgonda districts during the next 24 hours. Squally winds speed reaching 45 to 50 kmph are likely in Prakasham, Guntur and Krishna districts during the next 12 hours. The state of sea is likely to be rough along and off the coast. Fishermen are advised not to venture into sea.Heavy to very heavy rainfall is likely at a few places over coastal Andhra Pradesh and adjoining Telangana. Isolated heavy to very heavy rainfall is likely over north coastal Tamil Nadu, Kerala, Lakshadweep, Rayalaseema, the rest of Telangana and Nicobar Islands.
