Because of the spatial distribution of oil inside the flooded area, it was not solely the buildings with oil tanks that had been affected but the spreading of heating oil mixed with the floodwater also led to air pollution in surrounding buildings. In the United States, an integrated strategy to real-time hydrologic laptop modelling utilizes noticed information from the U.S. The NWS also cooperates with Environment Canada on hydrologic forecasts that affect each the US and Canada, like in the area of the Saint Lawrence Seaway. Dozens of villages had been inundated when rain pushed the rivers of northwestern Bangladesh over their banks in early October 2005.
