Japan's weather officials say Tropical Storm Dolphin may bring heavy rain to areas along the country's Pacific coast later this week.
The Meteorological Agency said that as of 3 a.m. on Tuesday, Japan time, Dolphin had a central atmospheric pressure of 992 hectopascals. It was packing maximum winds of over 80 kilometers per hour near its center.
The agency forecasts that the storm will slowly move northward and start to affect eastern and western Japan from Wednesday.
Officials are urging people to stay updated with the latest weather information to keep track of the rain and wind getting stronger.
