(AP) Tropical Storm Alpha formed Saturday in the Caribbean, setting the record for the most named storms in an Atlantic hurricane season and marking the first time forecasters had to turn to the Greek alphabet for names. The previous record of 21 named storms had stood since 1933. Alpha was the 22nd to reach tropical storm strength this year, and the season doesn't end until Nov. 30. At 5 p.m. EDT, Alpha had sustained winds of about 40 mph 1 mph over the threshold for a tropical storm. It was centered about 210 miles west-southwest of San Juan, Puerto Rico, and about 125 miles south-southeast of Santo Domingo in the Dominican Republic, and moving northwest at about 15 mph, the National Hurricane Center in Miami said. A tropical storm warning was in place for Haiti and parts of the Dominican Republic, and a tropical storm watch was in effect for the Turks and Caicos islands and the southeastern Bahamas.
