Global Hazards and Significant Events
Typhoon Neoguri was the season's earliest typhoon and perhaps the strongest early season typhoon to strike China since 1949. Additional information can be found below.
Across the United States, rainfall during April led to improving drought conditions in much of the Southeast region, but as of April 29, moderate to extreme drought remained over 43% of the region. Moderate to severe drought conditions persisted in most of the central U.S., while drought conditions in southwestern Texas worsened as a lack of precipitation led to further depletion of moisture. As of April 29, 37% of the western U.S., 30% of the South, 34% of the High Plains, and 27% of the contiguous U.S. were in moderate to exceptional drought, according to the Federal U.S. Drought Monitor.

Across China, moderate to severe drought conditions affected parts of south-central Tibet. Moderate drought was present across the northern Heilongjiang and the northeastern Inner Mongolia provinces (Beijing Climate Center).
Wildfires developed across much of the south-central states during mid-April. In Ordway, Colorado, a wildfire fueled by 80 km/hr (50 mph or 43 knots) winds, charred nearly 3,602 hectares (8,900 acres) of land and forced all 1,200 residents to evacuate the area (Associated Press). The fire destroyed 8 homes, 24 additional buildings, and was responsible for at least 3 fatalities: 2 volunteer firefighters and a pilot on a firefighting plane battling a blaze (Associated Press).

Hainan saw heavy rains that prompted flash floods across low-lying areas (BBC News). Neoguri weakened to a tropical storm prior to making landfall in the province of Guangdong in southern China. Three fatalities were attributed to the storm. Torrential rains produced by the storm caused a mudslide that killed 2 people and strong winds blew an aluminum sheet that killed another person (AFP).
