Dangerous wildfires were blazing across Oklahoma and Texas during mid-April, as strong winds up to 64 km/hr (40 mph) and dry conditions throughout the south central U.S. helped fuel the fires. Across Oklahoma, 200 homes were engulfed by the devastating fires and 34 people were seriously injured, while in Texas 32 homes were destroyed and three fatalities were reported (Source: CNN/AFP).
A massive wildfire scorched nearly 8,100 hectares (20,000 acres) in South Carolina's coastal area on April 22-24, resulting in the state's worst wildfire in nearly 30 years.

Heavy rains that affected Zambia and Namibia since March 2009 continued during April, wreaking havoc across parts of the region. The torrential downpours prompted the overflow of rivers, flooding homes and cropland, washing away roads, and increasing the risk of disease outbreaks. Nearly 700,000 people were affected in Zambia, while 344,000 people were affected in Namibia (Source: OCHA). The Zambezi River reached its highest level since 1969 (Source: IRIN).

Across the southern U.S., a major outbreak of severe weather and deadly tornadoes occurred on April 9-10, with 112 preliminary tornado reports along with many reports of hail and wind damage. As the storms progressed towards the east, the violent weather caused widespread damage across Alabama, Kentucky, Mississippi, and Tennessee and claimed the lives of five people—three in Arkansas and two in Tennessee. EF1-EF3 tornadoes ripped through western Arkansas on April 9, flattening homes, uprooting trees, rupturing gas lines, and downing power lines. The worst hit area was the city of Mena where an EF3 tornado killed three people and destroyed or damaged over 600 homes (Source: Associated Press).

Across the midwestern and south central U.S., severe storms swept through the regions during April 25-27, spawning tornadoes and producing nickel- to quarter-size hail and ferocious winds. On April 25, the O'Hare International Airport in Chicago, Illinois, was forced to cancel nearly 100 flights due to bad weather. High winds downed power lines, leaving nearly 123,000 homes without electricity across southern Michigan on April 26.

Tropical Cyclone Jade developed as a tropical depression northeast of the island of Madagascar on April 5, quickly intensifying into an Indian Ocean severe tropical storm (equivalent to a North Atlantic category one hurricane) that same day. Jade's maximum sustained winds were 120 km/hr (75 mph or 65 knots). The storm made landfall in northeastern Madagascar on the 6th, where it rapidly weakened as it tracked towards the southwest. Heavy downpours from the storm triggered deadly landslides and prompted a house to collapse. Over 33,300 people were left homeless and nine fatalities were blamed on Jade (Source: AFP). The storm exited Madagascar on the 7th.
Tropical Cyclone Bijli, the North Indian Ocean's first tropical cyclone during the 2009 cyclone season, developed April 14 as a tropical depression. Bijli intensified to a tropical storm on the 15th and by the 16th it reached its maximum sustained winds near 93 km/hr (58 mph or 50 knots). Although the storm did not make landfall in eastern India, its outer rain bands dump heavy rain across the region. The storm continued its northeast track, making landfall in southern Bangladesh on April 17. The cyclone brought heavy rain and strong winds, but by the 18th weakened in intensity as it moved towards Burma (Myanmar). Bijli was responsible for damaging homes and crops and claimed the lives of five people (Source: Muslim Aid).
