Japan's weather agency issued a special heavy rain warning for the Izu island chain south of Tokyo on Thursday, cautioning about life-threatening conditions and urging residents to remain vigilant for landslides and flooding, according to Kyodo News.

According to the NHK, the Japan Meteorological Agency said that "the kind of heavy rain that people have never experienced before is threatening to life. They are calling on people to evacuate immediately for their safety."

The Japan Meteorological Agency's alert covered Hachijo Island, some 280 kilometers south of the Japanese capital, with Typhoon Halong bringing strong winds and heavy rain to the remote region as it moved in a northeasterly direction over the Pacific. The warning called on residents to take immediate steps to find safety, per Kyodo. 
 
The area could see winds of up to 180 kilometers per hour and peak gusts over 250 -- strong enough to destroy buildings. Bands of heavy rain clouds may form before noon, and the risk of disaster is expected to rise.The islands are expected to receive up to 180 millimeters of rain in the 24 hours through Friday morning, NHK reported.
