Hurricane season is underway, but the Atlantic Basin remains quiet. What's going on out there? Since the start of the Atlantic hurricane season on June 1, the Miami-based National Hurricane Center has reported no tropical cyclone development (aside from a tropical wave or two) in the Atlantic Basin - an area that includes the tropical Atlantic Ocean,

Data from the National Oceanic and Atmospheric Administration (NOAA) released in late May forecasts a 60% chance of an above-average hurricane season, with 13 to 19 named storms expected, including 6 to 10 hurricanes and as many as five major hurricanes.

The National Hurricane Center is monitoring three tropical waves in the Atlantic basin, including one in the western Caribbean.

The National Hurricane Center is monitoring two tropical waves in the Atlantic: Tropical wave 1: A tropical wave located at 37W from 02N-12N in the central Atlantic is moving west at 11 mph. Tropical wave 2: A central Atlantic tropical wave east of the Caribbean Sea has its axis along 57W south of 17N, is moving west at 11 to 17 mph.

A developing tropical cyclone is given a name when it reaches sustained winds of 39 mph, and it becomes a hurricane at 74 mph.

The low-pressure area the NHC has been monitoring off Florida's eastern coast will bring heavy rain to the Carolinas before fizzling out.

The first hurricane in the Pacific doesn’t typically arrive until the last week of June. Three have been named so far this season.

Tropical storms feed off heat and moisture, and that begins with warm ocean water—at least 80°F (27°C). But it’s not just about the surface. That warmth needs to extend 150 feet or more below the surface to sustain a growing storm.
