BirdCast predicts medium to high migration traffic aloft over an extensive areas of the central US from Mexico to Canada this weekend. Let's take a look briefly at why we think this will happen, and what species will be on the move.
A strong cold front will move through the central US and bring precipitation and northerly winds to the Gulf of Mexico region. These factors are typically associated with coastal fallouts in many different habitats. Saturday and Sunday will be the primary fallout potential in the western Gulf region, whereas Sunday and Monday will be that potential in the east Gulf region.
In this short post we highlight tonight's migration forecast in the West. Conditions are favorable for movements from the Desert Southwest north and west along the Pacific Coast into Washington state.
