I'm still waiting for pictures, but this is one of the few articlkes that assess the damage:
At the end of the article, they note:
"If we don't provide an immediate solution, in the next storm the site at Caesarea is liable to collapse totally, including more of the ancient port, the aqueduct, the city wall from the Byzantine period and so on. Even the Roman theater has been left defenseless. If it is hurt, [singer] Shlomo Artzi will have to find another venue for his performances."
