Amazing drop in the SOI index--now at a very low -49 from a positive 18.  That's a 57 point drop.  What will be even more amazing is if it runs back.




Xray activity continues to be low with a blank sun and no coronal holes.


There is some activity in the EPAC, but it is so far offshore it's more related to the displacement currents coming from the WPAC than from the Americas--which gets back to the strong affect of El Cajon.  There is another dam here, too--Three Gorge.  In my view both the EPAC and the WPAC get suppressed at this time of year due to both those dams.

Meanwhile, we continue to have dry season rain on the left coast.

There is an invest in the WPAC (98W) that is more likely to fire up than the one in the EPAC, due to the SOI the way it is, but with so little xray activity, it may take some time.
