On this day in 1979 the lowest atmospheric pressure at the center of a cyclone, 870 mbar (25.69 inHg), was recorded for Typhoon Tip. Known in the Philippines as Typhoon Warling, Tip remains the largest and most intense tropical cyclone ever recorded. At the storm's fullest extent, its diameter reached 2200 km. That's large enough to cover the entire continental US west of Texas. Typhoon Tip made landfall on 19 October in Japan, where it caused flooding, damage and 86 deaths onshore and offshore.
