SEATTLE – Blue Angels, hydros, Mariners, Seahawks, Storm and bridge closures are going to make it a busy weekend for travelers in and around Seattle.

The Navy's aerial precision flying team will be holding both of its shows over Lake Washington this weekend. As usual, the I-90 floating bridge will be closed from 12:45 p.m. to 2:40 p.m. on Saturday and Sunday during the performances.

The bridge will be closed to cyclists and pedestrians 30 minutes before the posted closing times.

Once the bridge is cleared Saturday, travelers will start merging with Seahawks fans headed to the scrimmage at the Seattle Center Memorial Stadium. It starts at 5 p.m. Tickets are $12 for adults and $5 for kids 6 to 17 years old, and kids 5 and under are free.

A couple hours after that, the Seattle Storm host the Phoenix Mercury, virtually next door at KeyArena. Tip-off is 7 p.m.

The Mariners are home this weekend against the Boston Red Sox. The final game of the series is at 1:05 p.m. Sunday, the same time as the I-90 bridge closure.

The hydros hit Lake Washington for the Chevrolet Cup on Sunday. Dave Villwock in the Elam Plus is trying for a season sweep on the unlimited hydro circuit.

Police crack down on drunken Seafair boating

Seattle Police Harbor Patrol officers call it the "break-in" - the moment after aerial acrobatics conclude each day during Seafair weekend and the part of Lake Washington that has been closed during the flyovers reopens to boaters.

Everyone rushes to get the perfect spot for their weekend recreation.

"Of course they have been drinking earlier in the day and as they move into the break-in, we are already catching people who are drunk," Officer Matthew Nichols said. "It gets really hectic really quick."

Nichols said the break-in each day of Seafair is one of the key times when law enforcement officers look for boating violations, including speeding and drunken boating.

Seattle's Harbor Patrol is one of a handful of agencies that are part of a small flotilla of law enforcement officers taking a no-nonsense stance on boating while drunk during Seafair activities Friday, Saturday and Sunday. About 50 officers from the various agencies will patrol Lake Washington with 13 vessels.

Last year the Coast Guard said it contacted 408 vessels at Seafair and made 132 arrests for boating under the influence.

With an estimated 20,000 boats on the water for Seafair and possibly 350,000 people on or around the lake, Nichols said law enforcement officers expect to stay busy.

Sgt. Keith McDonough of the Mercer Island Marine Patrol said police will be looking for a few telltale behaviors during their patrols on Lake Washington, especially boats that are speeding and leaving a wake.

The blood alcohol legal intoxication threshold on the lake is the same as on land at .08, but being on the water under a sunny sky can change the way people react to alcohol, McDonough said.
