The NHCcontinues tracking three tropical waves that are moving west across the Atlantic and the Caribbean but doesn’t expect any tropical development.

In the Atlantic basin, the National Hurricane Center is watching three tropical waves, including one in the Caribbean.

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

Atlantic Hurricane Season began yesterday. Most of the Atlantic basin is quiet for now with thick Saharan dust moving across the Atlantic Ocean. However, we are monitoring an area of disorganized showers and storms around the Florida peninsula.

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

Cosme was a tropical storm in the North Pacific Ocean Monday afternoon Mountain time, the National Hurricane Center said in its latest advisory. The tropical storm had sustained wind speeds of 70 miles per hour.

Along with Saharan dust, rain can be expected to continue in some locations, along with higher temps and a heat index in the triple digits.

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.
