Updated 6:24p: Incredible weather has just passed through Treasure Island meeting all the strong and severe expectations that the National Weather Service forecasted, as well as setting a new record on my weather station.
As of this post the severe line of storms has passed Treasure Island but the weather is not done yet since extremely strong winds are forecast for this afternoon with gusts up to 50mph possible.
The storms that did pass through so far have set off numerous alarms and even suprized me at their intensity. I should learn to start trusting my own SmartForecast because once again it was right on the nose for intensity, wind speed and rainfall ammount. It predicted strong to severe storms, 35mph gusts and 0.75 to 1.00 inches of rain.
Actual observations before/during line of storms:
- Average Wind Speed: 25mph
- Peak Wind Speed: 31mph (set this peak at 2:08a, 2:22a, 9:06a)
- Temp 75 / Dew Point 72 / Humidity 93% for over 12 hours
- Minimum Barometric Pressure: 29.65 at 9:00am
- Peak Rainfall Rate: 9.000 inches per hour!* (new record at 9:21a)
- Sustained rainfall rate exceeding 5.0 inches per hour for seven minutes!
- Total rainfall in 20 minutes: 0.82 inches (9:05a-9:25a)
- Total rainfall in 1 hour: 0.88 inches (9:00a-10:00a)
Other observations from around the area:
- 44mph Wind Gust at Albert Whitted Airport (9:12a, 8.0mi East from my location)
Observations after the line of storms:
- Peak Wind Speed: 33mph from the WNW (3:26p, 4:45p, 6:24p) **
- UV Index Peak: 11.3 (just 0.6 shy of the record set 4/14/07)
- Solar Radiation Peak: 1238 (just 3 w/sqm shy of the record set 3/29/07)
*Rainfall rate record for ALL TIME: 13.3 inches per hour set on 04/24/03
This rainfall rate sets the new high record for my new weather station and sets my 2nd all time high for rainfall rate since I began observing weather with instruments in March 2003.
**Tied for my new weather station‘s high wind speed that was set on 3/1/07 of 33mph. All Time high wind speed is 38mph measured with my old weather station on 6/12/06 during a tropical storm, however this measurement is likely to be lower than actual due to inferior hardware at the time.
I will keep this post updated with new information since the interesting weather has not completely passed yet. Very high winds are forecast for this afternoon along with minor coastal flooding. Since I live on the coast I will definately post the interesting information regarding that here.
