Jamaicans love to spin a yarn. I was ON the beach during Gilbert and there was NO TSUNAMI at all. But it is a heck of a fictional story. No one was dragged out to sea and disappeared. The loss of life happened mainly due to landslides, and people were buried and never found. But NOTHING like what you described happened on the beach. Not even close. The water rose at a relatively slow rate.
On Gilbert's 30th anniversary, I wrote a "blow by blow" account, not fictionalized in any manner. Except for a couple mistakes my sister pointed out about when we arrived back in the States, this is actually what happened during Gilbert. And tomorrow looks to be a repeat of the action, but with hopefully less damage due to the lesser strength. Gilbert arrived as a 4 and left the Negril Beach as a 3 with the eye passing directly over our heads - a truly unbelievable sight. Beryl should hit the island at a 3 in Kingston and depart once again on the Negril beach at a Cat 2.
