Hurricane Rafael is rapidly intensifying as it approaches Cuba and the Gulf of Mexico, having recently strengthened to a Category 2 hurricane. Warnings are in place for the Florida Keys as the storm, initially a tropical storm, has progressed through the Caribbean, impacting areas like the Cayman Islands. As Cuba braces for potentially damaging winds and life-threatening storm surge, preparations are underway for landfall, projected for Wednesday. The storm is anticipated to affect oil production in the Gulf and could bring heavy rainfall to parts of Florida. Authorities continue to monitor the situation closely.
