A tropical storm could potentially damage some of the work at the site of the BP oil spill, experts say.

The bad weather around the Caribbean may gain some momentum, and could move to the site in Gulf of Mexico, forcing ships to be withdrawn.

This could mean that work will be stopped on the well for up for two weeks.

Some final casing needs to be cemented into place at the bottom of the relief well before it can drill into the damaged well.

Once the cement is in place, engineers could start drilling with in a week and “kill” the well with mud and cement.

There is a 60% chance that the weather that is over the island of Hispaniola will turn into a cyclone in the next two days, the National Hurricane Center says. It is moving West-northwest.

If the weather abstains, a “static” kill, pumping mud into the well through the new cap, could be done as an intermediate measure. BP and government experts are deciding if this will take place.

The cap was attached last Thursday and stopped the oil leaking from the well for the first tiem since the Deepwater Horizon drilling rig exploded on April 20.

Eleven workers were kill on the BP-leased rig and the oil has caused one of America's worst environmental disasters.

The well is having an integrity test performed to see if there are any ruptures beneath the surface.

Admiral Allen said BP and the government are still discussing if the will be be closed as it is or opened in the event that bad weather push the ships away from the well site.

An enormous amount of oil has leaked into the Gulf and BP says they have paid out close to $4 billion so far.

BP is in the process of liquidating assets in Texas, Canada and Egypt to make their ends of the clean-up meet.
