The CSU projects that another 13 named storms will form and accounting for the early development of Alberto in May, the final season total is expected to be 14. It dumped heavy rains in Cuba. Scientists note that even an average or below average season can produce storms that devastated areas where they make landfall and caution against taking the wrong message from a reduced forecast.
