The National Hurricane Center has highlighted an area in the northern Gulf Coast for possible development closer to the July 4th holiday.
"Towards the end of this week into next weekend, an area of low pressure could develop from a remnant frontal boundary near or along the southeastern U.S. Atlantic and or Gulf coasts," said the NHC on Sunday. "Some gradual tropical or subtropical development could occur thereafter as it drifts slowly just off the U.S. coastline."
Off the eastern coast of Mexico, Tropical Storm Barry has formed with maximum winds of 40 miles per hour. It is not a threat for the northern Gulf Coast.
Barry is expected to dissipate quickly after landfall.
"The primary impacts with Barry remain heavy rainfall and flash flooding for portions of eastern Mexico in upslope terrain as the system moves inland over the area of over the next day or two," said the NHC.
