Tropical Storm Erin is expected to intensify into a hurricane as it progresses across the Atlantic this week.

The National Hurricane Center’s forecast cone suggests a westward trajectory but does not definitively indicate whether it will impact the east coast of the United States. Spaghetti models, which compile predicted trajectories from various computer simulations, offer a clearer understanding as of Wednesday morning.

All major models indicate that the storm will pivot north and ultimately northeast before reaching the U.S. mainland, based on data and analysis provided by meteorologist James Spann.

As of Wednesday morning, Tropical Storm Erin has maximum sustained wind speeds of 45 mph and is advancing westward at 20 mph. It is anticipated to gradually shift northwestward on Thursday and attain hurricane status late Thursday night or early Friday morning, per the 5 a.m. ET Wednesday NHC forecast.

Currently, there are no coastal watches or warnings in effect.

The latest forecasts, updated multiple times each day, can be monitored online through the National Hurricane Center website.
