After a lull in tropical activity as we approached the statistical peak of the 2025 Atlantic hurricane season, the National Hurricane Center (NHC) is monitoring a tropical wave that's emerging off the coast of Africa that's producing a broad area of showers and thunderstorms.

Tropical Storm Mario formed off the coast of Mexico in the Eastern Pacific Ocean Friday morning, threatening heavy rain and some potential for flash flooding along the coast's higher terrain.

Environmental conditions are only marginally supportive. Warm sea surface temperatures are favorable, but the system will likely contend with dry air (including Saharan dust) and some wind shear, which could limit how quickly — or even whether — it organizes.

Tropical Storm Fernand is forecast to weaken as it churns over the open Atlantic Ocean, and odds have plummeted for a system to develop near the eastern Caribbean.

A tropical wave producing a cluster of showers and thunderstorms just off the coast of western Africa continues to hold the attention of the National Hurricane Center for future development, but overall the Atlantic Basin remains unusually quiet for being right at the peak of the hurricane season.

A disturbance over the eastern tropical Atlantic could gradually develop into a tropical depression or named storm by late this week or weekend as it moves generally west to west-northwestward.

The National Hurricane Center on Saturday continued to give a tropical wave in the Atlantic a medium chance it would develop into the season’s next tropical depression or storm. As of the NHC’s 8 a.m.

Like Kiko, the center of dozens of storms passed close enough to leave impacts from winds, rain and rough seas. They've even contributed to wildfire risk, such as the wildfire that devastated Lahaina, Maui, in August 2023.
