The Atlantic Hurricane season is so busy this year the names have all been used up and now forecasters must use the Greek alphabet.

That’s why this storm is called Delta (4th in the Greek alphabet).

Louisiana is now preparing for the 4th landfall this year and keeping with the “4” theme, the storm is now a Category 4 Hurricane.

However Mexico’s Cancun is most exposed to the storm over the next couple of days and may hit the tourist resort area as a major Category 4 hurricane.

US forecasters suggests a little weakening as it moves in to the USA with latest tracking suggesting it could hit as a Category 3 storm, the same power that Katrina had back in 2005.

WeatherWatch.co.nz head forecaster Philip Duncan says this is the 25th named storm of the season. “The last and only other time the Greek alphabet was used to name Atlantic storms was in the busy 2005 season, the year of Hurricanes Katrina and Rita. That year hurricanes were still forming in winter and into January 2006”.
