Japan Faces Intense Heat Wave and Approaching Typhoon

On July 29, Japan found itself under the grip of an intense heat wave, with temperatures forecasted to hit 39 degrees Celsius in several regions. The Japan Meteorological Agency indicated that those in Yamanashi, Yamagata, and Gifu prefectures would likely experience the most severe effects of the heat. By 9 a.m., over 400 locations across the country had already surpassed 30 degrees amidst clear skies, leading officials to advise residents to prioritize their health by finding shade and using air conditioning during the hottest hours.

The JMA attributed this unusual heat wave to shifts in wind patterns, explaining that the westerlies are migrating further north than typical, allowing warm air from the south to engulf the Japanese archipelago. Furthermore, a potent high-pressure system over the Pacific is coinciding with a strong Tibetan high-pressure system creeping in from the continent, creating ideal conditions for rising temperatures. These factors are particularly effective in regions that receive extensive sunlight as they cause warm air to descend.

Looking ahead, the JMA cautioned residents that the extreme heat is expected to persist for another week, with elevated temperatures projected to last nationwide until October. In addition to the temperature concerns, Typhoon No. 9 was anticipated to approach the Ogasawara islands by the evening of July 29, threatening the area with severe weather until July 31 as it made a gradual approach. Should the typhoon veer north, it might affect the Pacific coast of Honshu, bringing high winds and heavy rainfall, especially to the Kanto region starting August 2.

Despite the uncertainties surrounding the typhoon's path, a JMA representative emphasized the importance of staying informed about the latest weather updates. As of 10 a.m. on July 29, the typhoon was reportedly moving northwest, positioned about 110 kilometers northeast of Chichijima island, with noticeable wind speeds reaching up to 108 kph and gusts reaching 144 kph. Authorities warned those in the Ogasawara islands and nearby maritime areas to prepare for strong gales, elevated waves, and potential landslides due to heavy rains extending through July 31.
