Strongest tornado hits Mineral Wells, Texas, where disaster was declared. Elsewhere, extreme rain inundates China

Spring is the season for severe thunderstorms across the central US, and the start of this week was a particularly active period for the region. A favourable weather pattern fuelled intense thunderstorms on Monday through Wednesday, bringing strong winds, very large hail and strong tornadoes.

Eight tornadoes were reported on Monday, including an EF2 tornado that ripped through the town of Sycamore, Kansas. On Tuesday, a more widespread event tore across the mid-west, most notably as a severe hailstorm moved through Springfield, Missouri.
