Storm Dennis continued to pummel parts of England, Wales and Ireland over Sunday night with heavy rain after battering Northern Ireland and Scotland, per the official British weather agency the Met Office.
Why it matters: It's the second-strongest nontropical storm ever recorded in the North Atlantic Ocean, with its hurricane-force winds and heavy rains that caused widespread flooding across the U.K., the Washington Post notes. Police in Wales confirmed Sunday they found the body of a man who fell into a river as the storm lashed Ystradgynlais.
