PDC Weekly Global Flood Survey: January 12, 2012
Looking at precipitation and flooding over the last week, the Pacific Disaster Center (PDC) Global Hazards Atlas shows rainfall over the last 7 days. As you can see, south central Africa has had widespread showers, which have become heavy as they moved offshore to Madagascar. Southeast Asia have experienced areas of considerable precipitation. Locally heavy precipitation has also impacted Australia, augmented by tropical cyclone Heidi, which brought heavy rains and localized flooding as it moved ashore near Port Hedland in northwest Australia recently.
According to the United States National Weather Service (NWS) Climate Prediction Center, La Niña conditions will continue in the light to moderate range through the spring season of 2012. During a La Niña event, we can expect trade winds to pick up, pushing warm water westwards towards Indonesia and the western Pacific. As a result, wetter than normal conditions are predicted for northern Australia and Indonesia from January – February.
La Niña will potentially make for wetter than normal conditions across parts of southern Africa. In South America, northern Brazil can expect wetter than normal conditions while the west coast of the continent can expect drier than normal conditions. In the United States, La Niña events usually result in wetter than normal conditions across the Pacific Northwest and drier and warmer than normal conditions across much of the south.
PDC will be monitoring areas of high precipitation and keeping a close eye on flooding across the globe. Currently PDC is monitoring significant flood events in: Angola, Australia, Bolivia, Brazil, Ecuador, England, Malaysia, Thailand, Southern Peru, Philippines, Scotland, Madagascar, Mozambique, and the United States.
