Forecasters warned Gulf Coast residents Saturday to keep an eye on the tropics, where a disturbance threatened to become Tropical Storm Michael later in the weekend.

In its 8 a.m. statement the National Hurricane Center in Miami said that satellite photos, surface observations and radar data indicted that an area of low pressure just off the coast of Honduras in Central America was becoming better organized, although it did not have a well-defined circulation.

The Hurricane Center said environmental conditions were becoming more favorable for the disturbance to become a tropical cyclone, possibly on Sunday or Monday.

It urged people in the Yucatan Penninsula, western Cuba and the northern Gulf Coast to keep on the system.

As of Saturday it was moving north and posed a 90 percent chance of development within five days.
