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.

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.

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.

Barbara is the second named storm to form in the Eastern Pacific in 2025. Storms that form in the Atlantic or the Pacific generally move west, meaning Atlantic storms pose a greater threat to North America. If a storm forms in the Pacific close to land, it can bring damaging winds and rain before pushing out to sea.

When La Niña sets in during hurricane season, it has the potential to dramatically increase both the number and strength of tropical storms and hurricanes in the Atlantic basin.

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.
