Four notes for tonight from the WSB West Seattle Event Calendar:

BLOCK WATCH CAPTAINS TAKE ON 911: Seattle Police communications Capt. Sean O’Donnell comes to the West Seattle Block Watch Captains Network tonight, 6:30 pm at the Southwest Precinct, to talk about how 911 works “behind the scenes” – and answer your questions. (Webster west of Delridge)

LINCOLN PARK SAFETY WALK: 7 pm, join the West Seattle Crime Prevention Council and SPD/Seattle Parks reps in the north lot of Lincoln Park to head out on a “safety walk” in the park. (Fauntleroy/Rose)

LOW TIDE: Last day of low-low tide – 2 pm, it’ll be out to -2.8 feet; not as low as the past few days but still very good for GENTLE tidewalking. 11:30-3 pm, you’ll find Seattle Aquarium beach naturalists at Constellation and Lincoln Parks.

SEALTH OPEN HOUSE FOR INCOMING NINTH-GRADERS: Know someone going into 9th grade at Chief Sealth International High School next year? Tonight’s the special open house, 6-7:30 pm in the Galleria, previewed here recently – a chance to talk about sports at the school, whether the student already plays one or more sports, or is just thinking about it! (2600 SW Thistle)
