I'm sorry I overlooked your email requesting that I read and review this poem. It wasn't intentional.
It isn't easy writing a form poem that has to adhere to a specific syllable count, but I think you did a pretty good job. I'll address the form of the poem first.
The Nonet is a 9-line poem with the first line having 9 syllables, and the syllable count descending per line. The traditional style is written in only one stanza. Yours has two, where you reverse the style in the second stanza. Calling this a Reverse Double Nonet seems quite accurate. Cynthia BuhainBaello wrote a poem called "You And Me" on PoemHunter.com, she wrote it in the same style you did and called it a Double Nonet Poem.
You accomplished the required syllable count until the second stanza.
last night anyone die? (should have only 5 syllables)
helping neighbors cleanup
Both of these lines have 6 syllables.
Now let me address the readability of the poem. I found the first stanza very descriptive of a terrible storm. I love the image of the "greedy fingers". But the second stanza was awkward and difficult to read.
I also found the title misleading, as the poem is more about a raging storm that passes through, doing immense damage, not simply about "Storm Clouds".
I felt the poems' lack of punctuation caused some of the choppy feel and caused the difficulty in the reading. I've added some punctuation below to show you what I mean.
Clouds, heavy with blackness, funnel down
greedy fingers threaten snatching
the countryside, flattening
Ted's barn, Jo's spring flowers,
Wilfred's Repair Shop. (this appears to be the completion of the thought)
through rubble. (also the completion of a thought)
last night anyone die? (line suggestion: "Did anyone die?" 5 syllables, also less clumsy)
helping neighbors cleanup,
ignoring the storm of hate
brewing in their hearts, forgetting
their neighbors doesn't mean just next door.
The last 4 lines are awkward and choppy. I understood some of what you were saying, but the demands of the syllable count seem to have hindered the natural flow of speech and meaning. For example:
ignoring the storm of hate
brewing in their hearts Why is there hate brewing in their hearts and for who or what?
their neighbors doesn't mean just next door. (awkward wording)
Why are they forgetting their neighbors, when they are working together to clean up the rubble left behind by the storm?
I think, overall, this poem is a great attempt at writing a Nonet. The first stanza successfully portrayed the devastation of the terrible storm. But work needs to be done to the wording of the second stanza to make it flow easier and relay a clear message of the cleanup during the aftermath.
I enjoyed reading this poem.
