TAMPA, Fla. (WFLA) — Tropical storm Erin is expected to become a hurricane by Friday, the National Hurricane Center said.
Erin is moving west at 5pm and will continue this move today before moving towards a west-northwest movement tonight and weekend.

Erin’s centre is expected to move near or north of the Northern Leeward Islands over the weekend, the NHC said.
The maximum sustained wind is close to 50 mph.
According to the NHC, there is a high possibility that it will be Friday and Saturday, with a gradual strengthening expected the next day or so.
There are no valid coastal clocks or warnings.

Low-pressure areas near the west coast of the Yucatan Peninsula are causing disturbed showers and thunderstorms, the NHC said.
The obstruction is expected to emerge from the coast this morning and move west-northwest across the southwest Gulf coast the following day or two days.
According to the NHC, environmental conditions encourage further development as the system moves.

The system is expected to move inland through northeastern Mexico by Friday, ending the possibility of formation.
The chance of formation over the next 48 and 7 days is 20%.
