The mention was actually of giant hurricanes, Wizard.

More on this subject from the April 20 communication:

"Waiting until after a major cataclysm is too late. What you have already blinded yourselves to, is that you are already in the earth changes. You have already seen the beginnings of these major changes in your world, but only in the physical. The physical are the most evident: the tsunami in Indonesia was one example of that. There were 300,000 peoples’ lives snuffed out within 20 minutes, and hurricane Katrina in your own country, changed the geography and social culture and economy of thousands of square miles in the southern states of your nation. Unbeknownst to you, that devastation has caused many other areas to be changed as well.

Had those populations known what was coming, they would have been more prepared for the reconstruction of their societies. Visiting and neighboring nations do not know how to provide assistance. They simply send medical aid and food, [and] then hope everything gets better. But how do you reconstruct a family? How do you build new families where families have been destroyed, where there only remains a father here and a mother there, a child here and another child there? How do you create bonded groups that were not born together, or did not make a life commitment?

How do you build a community where a community was destroyed? The kind of information and support that areas of devastation need is how to reconstruct the social fabric of their world. How then are you able to establish an educational system that will then sustain those new families, those new communities? What will you do, what models will you use to establish a medical treatment model that sustains your people, the mental health, the social health and the well being of your communities? Though most of you do not know about sustainability or how to grow, we wish to assist you in developing models that can be applied to areas of destruction and devastation, to rebuild your social institutions so that they are not only rebuilt and maintained, but that they grow and grow heartily into something new and evolve into something healthier. This is what is needed for your world."
