I've lived next to the Gulf of Mexico all my life. Rip currents are only so deadly due to tourists (primarily) not being aware of how to escape them. They see themselves being moved away from shore and they panic and try to swim against the flow. They exhaust themselves and drown. Rips actually create small channels and funnel a flow offshore but those "channels" are usually quite narrow. If a person realizes what is happening and they turn 90 degrees and swim across the channel, they escape it pretty easily.
Just remember if one ever grabs you, swim parallel to the shore. You'll get out of it eventually.
I live about 3 hours or so from where 9 of these drownings have occurred - Panama City Beach - and those numbers are EXCEPTIONALLY high for an entire summer, let alone for a single month. Two dads died on Father's Day trying to save their child from the rip.
