Humberto is now a hurricane and the National Hurricane Center warns risks of impacts to Southeastern coast from two looming storms.

Humberto is about 465 miles northeast of the northern Leeward Islands and is moving slowly toward the northwest. It is expected to strengthen substantially over the weekend to become a major hurricane, the Miami-based U.S. National Hurricane Center said.

Humberto strengthened into a hurricane Friday morning and could reach major hurricane status by the weekend, the National Hurricane Center said.

Hurricane Humberto is forecast to become a major hurricane this weekend and a second system — likely to become Imelda — is a possible threat to the U.S. coast, especially the Carolinas.

As the National Hurricane Center tracks Hurricane Humberto, it's watching a tropical wave likely to become Tropical Storm Imelda.

Storm Humberto has reached hurricane strength as it churns across the Atlantic Ocean off the coast of Puerto Rico and Hispaniola.

Meteorological eyes are on a developing area of low pressure in the Caribbean Sea, watching to see how it will interact with Hurricane Humberto.

Tropical Storm Humberto expected to strengthen into major hurricane. Will Florida be impacted? That's hard to predict. Here's why.

Humberto is spinning in the west-central Atlantic, but the bigger question for the United States is what’s brewing next and how the two could interact.
