Hurricane Marco leading Tropical Storm Laura towards Gulf coast landfall
Hurricane Marco is forecast to bring hurricane conditions, with heavy rainfall and storm surge, along portions of the Gulf coast on Monday. Marco will be followed by Tropical Storm Laura, which is expected to bring additional wind, rain and storm surge impacts to the same region by mid-week.
It is highly unusual for two storms to make landfall in the same region in rapid succession. The map showing tropical storm force wind probabilities (above) demonstrates how the two wind fields are moving together, while the forecast wind swaths for both storms (below) shows the expected tracks impacting the New Orleans to Galveston section of the Gulf Coast (Marco is the upper right track, while Laura is the lower left track):
In addition to wind probabilities and forecast wind swaths, storm surge potential outlooks, precipitation-based flood potential outlooks and excessive rainfall outlooks are available in EigenPrism, giving you a complete picture of how these storms may impact insured locations.
Quick links for key wind footprints are shown below, and a template Impact Summary report for each storm has been created.
