Data from NOAA and Air Force Hurricane Hunter aircraft contributed to the National Hurricane Center (NHC) upgrading Zeta to a hurricane on Monday, October 26. AOML scientists supported all the NHC and Environmental Modeling Center (EMC) tasked P-3 and G-IV missions by processing and sending data. These missions investigated the location, intensity, and structure of Zeta and the storm’s interaction with its environment.
Scientists found a more aligned circulation based on analysis of the Tail Doppler Radar (TDR) data. This was an indication that Zeta was intensifying over the warm Caribbean waters. NHC issued a special advisory at 3PM EDT on Monday stating that Zeta had reached hurricane strength.
The NHC forecast predicts Zeta will make landfall in the Yucatan peninsula Monday evening. It is then expected to emerge into the coast sometime Tuesday morning. NOAA has one more G-IV flight scheduled for the early hours of Tuesday morning. This flight will be followed by continuous P-3 missions Tuesday and Wednesday until Zeta is predicted to make landfall along the Gulf coast.
