The brown ocean effect is an observed weather phenomenon involving some tropical cyclones after landfall. Normally, hurricanes and tropical storms lose strength when they make landfall, but when the brown ocean effect is in play, tropical cyclones maintain strength or even intensify over land surfaces. Australia is the most conducive environment for this effect, where such storm systems are called agukabams.

Tropical Storm Bill was a tropical cyclone that produced widespread rainfall across East Texas, Oklahoma, the Midwest, and Mid-Atlantic. The second named storm of the season, Bill developed from a broad area of low pressure over the northwestern Gulf of Mexico on June 16. Because the system was already producing tropical storm force winds, it was immediately classified as Tropical Storm Bill. Initially continuing northwestward, Bill re-curved west-northwestward later on June 16. Around 12:00 UTC, the storm peaked with maximum sustained winds of 60 mph (95 km/h). Just under five hours later, Bill made landfall near on Matagorda Island, Texas, at the same intensity. The cyclone weakened to a tropical depression and turned northward early on June 17. Bill remained a tropical cyclone until late on June 18, when it degenerated into a remnant low. The remnant low moved east-northeastward until dissipating over West Virginia on June 21.
