BHUBANESWAR, India (CNN) -- This time, residents on India's east coast have no choice.
Disaster officials don't want a repeat of a 1999 cyclone disaster that claimed 10,000 lives, so they are evacuating hundreds of thousands of people as a massive storm in the Bay of Bengal nears landfall.
"We have taken a zero-casualty approach," said Odisha state disaster manager Kamal Lochan Mishra. "If people do not move, force will be used to evacuate them."
Tropical Cyclone Phailin is expected to make landfall somewhere near the border of Odisha and Andhra Pradesh states in India by 8 p.m. local time (about 11 ET).
At least 440,000 people have now been evacuated from areas at risk, the country's National Disaster Management Authority vice-chairman, Marri Shashidhar Reddy, told reporters at a televised news conference early Saturday afternoon.
The storm is moving steadily across the Bay of Bengal and is now less than 40 kilometers (25 miles) from shore, the Indian Meteorological Department said.
It's expected to pack winds of up to 140 mph when it makes landfall and will bring a storm surge of as much as 6 or 7 meters (20-23 feet) in places, threatening densely populated areas that are vulnerable to flooding.
There are reports of seven deaths already in Odisha, as a result of falling trees brought down by strong winds, according to CNN's sister network in India, CNN-IBN.
Many of those evacuated from low-lying coastal areas of Odisha left on foot or by bicycle, Mishra said. Evacuations will continue until Phailin roars ashore, he said.
They are being housed in nearly 250 emergency shelters set up in sturdy buildings like schools and government offices.
The cyclone is expected to hit between Kalingapatnam in Andhra Pradesh and Paradip in Odisha, CNN-IBN said.
The Ganjam district of Odisha is expected to be the worst hit, with disaster preparedness efforts concentrated there, CNN-IBN reported.
In Gopalpur, a coastal resort town in Ganjam, restaurants were shuttered and streets deserted Saturday afternoon, as rain lashed down. Tourists as well as local resident have been asked to leave the town.
Power is out in coastal areas including Kalingapatnam, from where about 80,000 people have been evacuated to relief camps, CNN-IBN reported. Some fishermen told the broadcaster they had defied the order to leave, however, anxious to see what happened on the shore.
Residents further inland have been advised to stay indoors as the monster cyclone makes landfall.
Some fear a repeat of what happened on October 29, 1999, when Cyclone 05B, also known as the Odisha Cyclone, made landfall in the same area, causing the loss of more than 10,000 lives.
The strongest tropical cyclone recorded in the Bay of Bengal, it had winds of 155 mph at landfall and caused more than $2 billion in damage.
Phailin will be less intense than that at landfall and is likely to weaken more as it moves on shore, but will still bring storm surges and dump heavy rainfall on inland areas for the next two days.
The eye of the storm, which has been getting smaller in size, is expected to pass over the city of Brahmapur. The third largest city on the east coast, Visakhapatnam, is further from the center of the storm but will also suffer strong winds.
Hurricane-force winds are expected to last until noon Sunday, and could extend several hundred kilometers inland as the storm moves into India.
Military units and National Disaster Response Force personnel have been deployed with relief materials and medical aid in coastal districts in preparation for Phailin's arrival, CNN-IBN said. More than 20 medical teams have also been flown in to the region.
Federal and state government ministers are being briefed on the situation, the cabinet secretary said.
All flights to Odisha have been canceled and train services in the state are also disrupted, CNN's sister network reported.
International humanitarian organization World Vision said it was helping local community groups prepare for the cyclone's arrival.
"In a storm of this magnitude there is the potential for widespread damage to crops and livestock in the low-lying coastal areas and houses completely wiped away," said Kunal Shah, the head of World Vision's emergency response in India. "So while we are praying this storm loses intensity, we're also preparing."
The organization has worked for the past several years to train local people in disaster preparedness, including search and rescue, basic first aid and how to protect livestock, and has thousands of emergency response kits ready to hand out where needed.
"We believe communities are better prepared than they were when the devastating cyclone hit in 1999," said Shah.
The force of the storm
-- which is equivalent to a strong Category 4 hurricane -- could change the geography of the shoreline in places, creating inlets and eroding beaches, CNN forecasters said.
Rough seas, gales
The India Meteorological Department has warned that Phailin is a "very severe cyclonic storm" and urged the evacuation of coastal areas.
Gale-force winds are already whipping coastal areas of Odisha and north Andhra Pradesh and will continue to do so for hours after landfall, it said.
The storm surge could inundate low-lying areas of Odisha's Ganjam, Khurda, Puri and Jagatsinghpur districts and the Srikakulam district of Andhra Pradesh during landfall, it said.
Rainfall, some of it very heavy, started Friday in coastal Odisha and northern Andhra Pradesh and has now spread to inland areas of Odisha and coastal areas of West Bengal state.
Seas off the coast of Odisha and northern Andhra Pradesh have become extremely rough as the cyclone approaches land. Fishing operations are suspended, and all fishermen were advised to return to shore.
The meteorological department warns of extensive damage to so-called kutcha houses, those made of flimsy materials such as mud and bamboo, as well as some damage to old buildings.
Power and communication lines are likely to suffer large-scale disruption. Extensive flooding will also disrupt rail and road traffic, and crops are likely to suffer major damage, it said.
People in affected areas may be at risk from flying debris, as well as the flooding of escape routes.
