“This monsoon has been a little weird. We’re starting to see now what we were expecting in late June, early July,” he said. “In June, we were far more active than what we’d anticipated.”
Chatter around the National Weather Service office has raised a possibility: “The onset of El Niño is being looked at as a possibility of explaining the weather,” he said. Warming surface waters of the Pacific have been singled out as the cause of past major weather events.
The National Weather Service has measured surface water temperatures to be “about, on average, 1 to 2 degrees above normal,” Reedy said. That rise would be enough to cause the changes we’re seeing, he said.
If El Niño does turn out to be in effect, we may have a wet winter. “If this is a result of the El Niño, it may stifle some of the remaining precipitation for the rest of the monsoon, but it may help out in the winter,” he said.
