TAMPA, Fla. (WFLA) — As of 5 a.m. on Sunday, Hurricane Erin has weakened back to a Category 3 storm but has grown larger, the National Hurricane Center said.

The storm rapidly intensified to a Category 5 on Saturday, and the NHC said more fluctuations are expected over the next day or two.

Erin is now around 155 miles from San Juan, Puerto Rico and around 310 miles from Turks and Caicos.

It has also slowed down some since yesterday, now moving west-northwest at around 14 mph. NHC forecasts it will slow even more today before gradually turning north Monday and Tuesday.

A tropical storm warning is in effect for Turks and Caicos, and stormy conditions are expected within the next 24 hours as Erin passes by. A tropical storm watch is in effect for the Southeast Bahamas, with stormy conditions possible in the next 24 hours as the islands get lashed by the outer bands of the hurricane.

With maximum wind speeds back down to 125 mph, Erin is once again a Category 3 storm, but continued changes in intensity are expected. NHC said the storm is getting bigger, with hurricane-force winds extending 25 miles from the center and tropical storm-force winds extending up to 205 miles.

More heavy rainfall is expected for the Virgin Islands and Puerto Rico, potentially totaling up to eight inches. Local flash flooding as well as landslides or mudslides are possible.

Swells from the storm are affecting portions of the Caribbean where Erin is passing by and will likely spread to the Bahamas, Bermuda, the East Coast of the U.S. and Atlantic Canada through the beginning of the week, NHC said. Rough ocean conditions are likely to cause life-threatening rip currents along the Atlantic Coast beaches.

NHC has also identified another tropical wave coming off the coast of Africa. As of now, it’s just an area of disorganized storms, but a more structured area of low pressure could form over the central Atlantic during the middle to latter part of next week. The chances of formation over the next seven days are low, at around 20%, and the NHC gives it a zero chance of formation through the next 48 hours.
