Following the recent strong El Ni{\~n}o, however, we documented the arrival of three strong year classes in 2015, 2016 and 2017. Average catch rates in over the last three years steadily increased from 0.5 to 0.8 and to 1.9 crabs per trap. These catches are much higher than in any of the previous years, including 1998. Since green crabs live for 6 years, these three consecutive year classes will provide larvae until 2023.

The realization that El Nino can bring havoc to our coast has been strongly reinforced by the 1997-98 occurrence. Beach and property erosion has been severe at a number of sites along the Oregon coast, recurring in areas that previously had suffered during the 1982-83 El Nino. The objective of this paper is to briefly examine the coastal processes enhanced by El Nino that are important in producing erosion along the Oregon coast. While measurements during the ongoing El Nino are still being collected and analyzed, it is evident that the processes are remarkably similar to those experienced during 1982-83. The main focus of this paper will be a description of the erosional "hot spots" experienced during the 1997-98 El Nino along the Oregon coast.
