Memorial Day Holiday Weekend Forecast GSL Slip Renters and Marina Users. I have had some requests for my opinion on the weather forecast for Great Salt Lake this weekend. So I have provided a forecast for Memorial Day weekend. Realize that I am not a meteorologist so this forecast may not be worth the garbage that it may be. The forecast is based on my interpretation of all the weather charts I look at during the day. It is also focused on the general marina area but does have some applications for the whole Great Salt Lake So here it is for what its worth: Current Conditions Lake Level 4195.9 Lake Level Trend Steady Water Temperature 58 degrees Current Flows Most currents are running low to moderate but may pickup by Monday. Snowpack 97% Moon Stage Mostly full but waning Saturday Cloudy and remaining cool High 63 degrees Max Real feel 60 degrees Winds (on the lake) S at 10 mph gusting to 20 mph (might have a north flow at the marina) Maximum UV 5 Thunderstorm Probability: Low (19%) Amount of Precip. 0.02 Hours of precip. 1 hour Prob. of precip (1am to 4am) 40% Prob. of precip (4am to 7am) 50% Prob. of precip (7am to 1pm) 25% Prob. of precip (1pm to 7pm) 7% Sunrise 6:04pm Sunset 8:46pm Sea conditions: Generally light near the marina. light to moderate southerly swells farther north. Water temperatures: Mid to high 50's Hypothermia index: Exhaustion or unconciousness in 1 to 2 hours / death in 1 to 6 hours General wind on the GSL will be dominated by a light to moderate southerly flow through the day although local areas may vary at times and thunderstorms may also temporarily affect the wind flow.

Take it for what its worth. Its mostly my guess. Keep informed by local weather sources such as NOAA, radio and television. Give me feedback. If you would like the forecasts for holiday weekends to continue, I will try to do them. If you don't, I will be happy to stop them Dave Shearer Harbormaster Great Salt Lake Marina Have you checked your docklines lately?
