Over the past week floods were observed in Africa (Uganda, Kenya), Australia (Queensland), Canada (Ontario, Manitoba), China (Guangxi), Central America (Guatemala), Europe (France), the Middle East (Saudi Arabia, Oman), the United States (Upper Great Lakes, North Dakota, Arkansas, Mississippi, Middle Mississippi Valley, North Carolina, South Carolina, Virginia), and Tasmania.

In the Northern Hemisphere, many regions are gearing up for the upcoming 2013 hurricane season, which begins May 15 for the East Pacific and June 1 for the Atlantic. In addition to destructive winds, tropical cyclones may also cause flood-related hazards such as: (NWS/NHC)

– “Storm Surge” is an abnormal rise of water caused by a storm’s winds. Storm surge can reach heights over 20 feet and affect hundreds of miles of coastline.

– “Storm Tide” is the water level rise caused by both storm surge and astronomical tide.

– Tropical cyclones may also cause “Heavy Rainfall and Inland Flooding”.  Tropical cyclones can produce rain in excess of 6 inches which causes deadly and destructive floods. Rapid water level rise and intense rainfall also cause flash flooding. Inland flooding continues to pose a risk for many days after a storm ends.

According to this week’s Africa Hazards Outlook (May 8-15, 2013), the risk for flooding is expected to continue in Kenya, Uganda, and Somalia. The chance of heavy rainfall over parts of Kenya and Uganda remains high throughout the rest of the week. Recent floods have displaced over 25,000 people and affected 57 different villages in the Kasese District of Uganda; many people remain unable to return home (Relief Web).

The Juba and Shabelle Rivers in Somalia have experienced above-average rainfall which has led to elevated water levels and increased flooding risk throughout the region (CPC). Rainfall is expected to continue throughout the region (FAO).

Looking Ahead

PDC is currently monitoring flooding events/threats in: Australia, Canada, France, Somalia, Uganda, and the United States.

PDC will continue to monitor areas of high precipitation and keep a close eye on flooding across the globe.
