MIAMI, Florida — Sunday, July 13, 2025 — About six weeks into the Atlantic hurricane season, forecasters are watching a developing weather system off the Southeast U.S. coast that could bring heavy rain to Florida and parts of the Gulf Coast in the coming days.
In its 8 a.m. advisory Sunday, the National Hurricane Center in Miami said a trough of low pressure is expected to form off the southeastern coastline and move westward across Florida into the northeastern Gulf of Mexico by Tuesday. While conditions aren’t currently favorable for significant development, the system could gradually strengthen later this week as it tracks across the northeastern and north-central Gulf.
At this point, the chance of tropical cyclone formation remains low—near 0% over the next 48 hours, and 20% over the next seven days. However, the main concern in the short term is heavy rainfall, which could lead to localized flash flooding in Florida and along the north-central Gulf Coast from midweek onward.
If the system does develop into a tropical storm, it would be named Dexter, next on the official list for the 2025 Atlantic hurricane season.
Three other tropical waves under observation
In addition to the Gulf system, the hurricane center is keeping tabs on three tropical waves across the Atlantic basin. Two are currently pushing westward across the eastern and central Atlantic, while a third is moving through the western Caribbean. As of now, none of these systems are expected to develop or pose any threat to land.
Hurricane season off to a quiet start
The Atlantic hurricane season officially began on June 1 and runs through November 30, with peak activity typically occurring between August and October. So far, it’s been a quiet start, but the pattern could shift as ocean temperatures continue to warm and atmospheric conditions become more favorable for storm development.
The USA TODAY Network in Florida is providing daily tropics coverage throughout the season, tracking all disturbances, advisories, and potential threats.

Forecasters will continue to monitor the disturbance and any potential development, especially as the season moves into its historically busiest period.
