High tides and dangerous conditions forced Cameron County officials to close Boca Chica Beach and South Padre Island TMs Beach Access Five and Six.
Law enforcement officers are standing guard at each location to make sure no one tries accessing those parts of the beach.
For the areas that do remain open, officials are asking visitors to be careful when entering the water because of rip tides.
The U.S. Coast Guard has deployed extra personnel and is getting ready to protect area visitors during Tropical Storm Don.
But before it hits, they were working to safeguard some of their own assets.
Coast Guard personnel spent Friday morning removing three of its five boats.
They are asking boat owners on the island to come and get those boats out of the water.
Although the Coast Guard will be here to respond to any emergency from Tropical Storm Don, they said their response time may be slower.
Petty Officer Carl Hammond spoke to Action 4 News about Tropical Storm Don.
"Typically, we have one to two minutes response time on emergency calls from this unit, and in this case, that's going to be significantly delayed in some cases, Hammond said.
Coast Guard officials said the tropical storm is expected to make waters very rough.
They say it could take up to 48 hours for the water to return to normal.
