After a powerful front moved thru with winds to 35 knots yesterday the wind lay early during the night. I took up my usual monitoring site, same as on the 24th, on the north approach peninsula to the Lavaca Bay Causeway, and counted five minutes inverals, first from 9:30 to 10:00 and then 12:20 to 12:50 ... again looking out the drivers front window and left window of the van ... sun was reflecting off the bay, made it impossible to see to right. From 9:30 to 10:00 the count was 297 monarchs for an average of 594 an hour, best for 5 minutes was 58. From 12:20 to 12:50 the count was 84 in 30 minutes for a 168 average in an hour, best 5 minutes was 22 monarchs. 594 monarchs an hour eclipsed the previous high of 190 an hour back on the 24th. I was monitoring a narrow 200' wide corridor. I drove backtracking and found the flow to cover about a five mile wide area crossing Lavaca Bay at this point. Good math problem. As the wind turned from NW to SE, the flow turned off by 3:00 pm.
