What does come thunder mean by Christopher Okigo?

The characteristic so his poems discussed in the background section hold good in the case of ‘Come Thunder’ too. The style, tone, and techniques used are much like those found in modernist poets. But the rhythm is essentially non-English. Abundant use of plosive sounds, in words and lines give a pattern to the poem. All this give the poem onomatopoeic effect which is in tune with the main motif of the poem - thunder.
