TAIPEI, Taiwan -- Two new tropical cyclones are gaining intensity as they head toward eastern Asia, already battered by flooding and high winds from devastating monsoonal weather conditions.

Taiwan issued sea and land warnings Tuesday as Tropical Storm Nakri moved with winds of 65 kilometers per hour (41 miles per hour) and gusts of up to 90 kilometers per hour (56 mph).

Nakri is forecast to slide west of Taiwan within the next 24 hours.

Officials say the biggest threat is from widespread flooding and mudslides as a result of heavy rain, already affecting southern China, Taiwan and the Philippines.

Meanwhile, Typhoon Chataan -- which triggered a landslide that killed dozens of people in Micronesia and left a trail of destruction -- continued toward Japan on Tuesday.

With winds of 180 kilometers per hour (112 mph) and gusts of 215 kilometers per hour (134 mph), Chataan is the most powerful of the tropical cyclones currently affecting the region.

A third cyclone, Tropical Storm Halong is moving in the general direction of Guam and Saipan in the Southern Marianas, with winds of 80 kilometers per hour (49 mph).

Earlier in the week, Typhoon Rammasun was downgraded to a tropical storm after causing severe flooding and the death of four people across the Korean peninsula.(Full story)

In the Philippines, the number of deaths from flash floods, landslides, and high seas triggered by Chataan and Rammasun, rose to 22 on Tuesday.

More than 24,000 people have fled their homes and sought shelter in evacuation centers in the capital Manila and neighboring provinces.

Government schools remained closed for a second day due to flooding, as the typhoon headed away from the archipelago.

In India an estimated 700,000 people have been caught in flooding in the northeastern state of Assam as rivers crested their banks and submerged low-lying shanties and huts.

In the eastern state of Bihar at least 10 major rivers, including the Ganges, are flowing above the danger mark.(Full story)

In Bangladesh, the final destination of more than 150 rivers that originate in the Himalayas and flow through India before reaching the Bay of Bengal, a week of monsoon flooding killed at least 11 people and marooned over half a million.

Flooding is spreading, with the rush of water from India's Assam and Meghalaya states forcing disaster officials onto "full alert".

Officials in Bangladesh confirmed eight people had died from diarrhea after drinking from floodwater in the southern district of Noakhali.

Both India and Bangladesh are anticipating worse to come before the monsoon season ends in September.
