PDC Global Flood Survey

PDC Weekly Global Flood Survey: March 29, 2012

Floods may occur for many reasons, including heavy rainfall, saturated soil, dam breaks, and the melting of large quantities of snow and ice. Many times it’s a combination of these factors that trigger a flood event.  In some cases, flooding may occur slowly, allowing plenty of time for warning and preparation. However, flash floods can occur with little or no warning, allowing limited time to prepare or respond.

Over the last week PDC has been monitoring flood events worldwide.  This week in Canada, large pieces of ice created natural dams which caused rivers to swell and overflow. In Australia weeks of continuous rain have saturated the ground in many regions causing the buildup of flood waters.

Regardless of the cause of flooding, it is very important for you and your family to always be prepared! For information on how to prepare your family to effectively respond to a disaster, check out PDC’s Disaster Checklist! For information on teaching your children how to prepare for disasters, look at PDC’s article ‘Parents Can Teach Kids about Hazards and Disaster Preparedness’!

Below we will take a look at flooding events currently occurring in Canada and The Philippines.
