Did anybody else noted this silver/black/thick hanging cloud over San Francisco today? Did not look like a usual cloud.

I am wondering whether anybody else noted this heavy kind of cloud today over San Francisco with a color of silver/black/dull white. It really looked terribly scary, it just did not feel like a regular cloud in S.F.
Did anybody notice that too?
WHat if this was a plutonium cloud? Would people who were within a 5 mile radius get radiation sickness?
How soon would we get sick, or would we not feel anything?
I am terrified. It just looked like a heavy smog cloud but different and did not go away even though the sun was there.
I noted an early comment from a reader who mentioned that too so I am not the only one who noticed it.

I noticed similar clouds on the east coast

Maybe I am just sensitive and am looking for odd stuff, but they looked more moinous to me. A friend in New Orleans said they had large hail this week too, which is kind of unusual i would think, but if the plume projections are correct, then this sh*t is everywhere in varying degrees in the atrmosphere from ground to space and I DO wonder whether it has any impact on the development of clouds or how they act (more rain due to more particulates, for example, or "hot" moisture in the clouds condensing in unusual ways.

Any thoughts on that Berkeley folks? Is there any data on how such amounts of xenon and cesium and iodine gas etc might alter clouds and how they behave?

Anyone else have any knowledge or noticed this? What with black water and rain and yellow rain speculations etc, I cannot help but wonder (and I am getting rain for the next two days! Yuck!

I want my soil and garden back whole and free of the Fukushima rain but it can't happen and I am seriously sad about this.

If it does not rain, though, will you know if it has radiation?

I mean, I know youy can detect the gases at ground level but does that automatically correlate to what the clouds consist of -- or does it have to rain?

I know dry precipitate (dust, I guess, or gaseous settling) would get picked up but MIGHT not the clouds aggregate radiation in higher amounts if the particulates are bound to or carried by the moisture so that the two might be very different "wafts" of the radionuclides where some is dry and others, more concentrated, are moist?

Am breahlessly awaiting new test results as I am HOPING for a downward trend.

according to detection reports I have seen (actual measurements from the folks who monitor for the test ban treaty) the west coast seems to peak three days before the east coast and then they decline about the same rate.

Please be respectful of the fact that UCB is supplying this data, as they are under no obligation. Imagine what it would be like without this service. They can compare it to whatever they want or see appropriate, as can you. I'm not affiliated with them, just extremely grateful for the service they are providing.
