Tracking Tropical Storm Erin

All eyes remain on Tropical Storm Erin as it continues to push across the central Atlantic.

Erin should become the first hurricane of the season before the week ends, and weather models are now leaning toward it steering well east off the east coast of Florida next week.

Residents in the northern Leeward Islands, Virgin Islands, and Puerto Rico should monitor the immediate progress of this system closely. While confidence in the forecast track is increasing, it’s still too early to determine potential impacts for the Greater Antilles, Bahamas, Bermuda, or other parts of the eastern U.S. coastline.

The forecast is becoming clearer with each update, and the Hurricane Hunters are scheduled to fly through Erin on Thursday to collect crucial data that will help fine-tune the track and intensity outlook. Warm ocean temperatures and low wind shear along Erin’s path are expected to support steady strengthening in the coming days. If the high-pressure ridge to the north weakens as expected, it would open a pathway for Erin to curve northward.

We are additionally watching the Bay of Campeche for a disturbance with a low (20%) chance of development. Early indications suggests a general a northwest movement for anything that forms there in the short term. Regardless, this wave is not expected to bring any impacts to Florida.

“Fernand” is the next name up on our 2025 storm naming list.

Tropical Storm Erin forms in the Atlantic

Tropical Storm Erin formed Monday morning with sustained winds up to 45 mph in the latest advisory.

Previously named Invest 97L, thunderstorms west of the Cabo Verde Islands have continued to organize despite Saharan dust concentrated nearby this disturbance.

The first cone is out for Tropical Storm Erin and shows it steadily strengthening.

Erin is moving west at 20 mph and will continue on this track the next few days. There is more uncertainty at the end of this week into the weekend.

The upper level steering will eventually support a curve north as it rides around the ridge of high pressure. There will be a dip in the jet stream that will help to nudge it north.

How far east of Florida and the Atlantic Coast will this happen? That is something we’re ironing out as we watch for this to form and see how model trends evolve.
