Hurricane Isaac? Lowest Radioactivity In a LONG Time

When we took our RadRoad trip to the Florida Keys, one thing we immediately noticed was that tropical storms blowing in from Africa had very little radiation in them.

Fast forward to today as tropical storm Isaac is blowing in to the Gulf of Mexico, we have had the lowest radioactive swipe  from a Saint Louis storm  since Fukushima exploded. That reading returned on 5x over background radiation; 3x is the max we would expect pre-Fukushima.

So far it is only a correlation, but the Jet stream map and surface winds suggest that Isaac is keeping the Fukushima winds at bay. If Issac continues to strengthen we may have a chance to take more data.
