A line of intense storms approaching the western Gulf Coast will make for interesting and challenging conditions for inbound trans-Gulf migrants. The strength and the timing of frontal passage, as well as its projected extent over water, suggest potential for larger fallouts farther south and west along the coast, in addition to those fallouts that occur farther north and east. One potential difference between these two broad regions will be species composition of the fallouts, with landbirds dominating farther to the south and west, and shorebirds and water birds dominating farther north and east. Additionally, large concentrations of diurnal and continuing migrants like Chimney Swifts, swallows, and Franklin’s Gulls will likely appears in significant numbers along the Texas coast after winds shift to the west and to the north, for those watching from home (everyone!).
Note, as the frontal boundary moves into the Gulf, potential increases in the coming 24-48 hours for fallouts east of New Orleans through the Florida Panhandle. We will be updating this post as potential and forecasts for these conditions become clearer.
