Four times Dave Bonta opens a stanza with the same plain announcement, "It's raining," and each time the rain means a little more than weather. On the surface, "March rain" is a series of small sightings on a thaw day. Underneath, it describes a change of power: winter's rule collapsing while a quieter, smaller kind of life takes over. Its central idea is that spring arrives less through fanfare than through the patient work of creatures and plants nobody is watching.
The refrain does much of the structural work. Like rain, it keeps returning, but never identically. The bare first "It's raining" grows into "the first warm rain of spring," which tells us what kind of rain this is. Then "it's raining, it's pouring" borrows the nursery rhyme and lets a childlike, playful note into the scene. The last stanza goes back to the bare phrase, which by now carries everything the earlier stanzas have loaded onto it. The stanzas also shrink, from four lines to four, then three, then three, so the poem tapers like a shower easing off, or like attention narrowing to smaller and smaller subjects.
That narrowing is the poem's real design. We begin with downspouts and a barn cat, things at human scale. Then come sap and bulbs, then worms, and finally an ant queen under bark. Each step goes lower and smaller, as if we were following the rainwater down into the ground. The sound changes with it. The opening is noisy: downspouts "gargle furiously," a verb that turns drainpipes into spluttering throats. By the end the pace is a "slow march," and the long vowels and heavy stresses of those words drag the line into steadiness. The loud thaw gives way to quiet persistence.
There is no rhyme. The free verse relies on short declarative sentences, and the two ampersands give the voice a jotted-down, notebook quality, as if the speaker were writing at a window. Instead of rhyme there is sound texture. The cat's line, "listens & licks her pregnant belly," is soft with l's and hushed after the clatter of the gutters. We learn nothing about the cat's feelings, only that she listens, and her pregnancy quietly hints that new life is on its way.
The imagery draws on two ideas, writing and empire. "Frogs of ice" is an odd, specific phrase. Judging by the context, it describes lumps of ice clogging the downspouts. Frogs are a classic sign of spring, so these frozen stand-ins suggest the season has to shape its creatures before it can wake them. The green shoots become "nibs," pen points, from which bulbs "will write / their deathless names in the air." The paradox is neat. Each bloom is brief, yet the bulb returns every year, so the signature is renewed again and again. It is also the only "will" in a poem otherwise anchored in the present tense, so it reads as a promise.
Then comes the language of empire. Winter's remains are "the muddy ruins / of once-grand palaces of frost," and the worms that "poke through" them are like explorers or scavengers wandering a fallen city. The final image answers this with another ruler: the ant queen, who "resumes her slow march." Her title and her military verb make her a successor to the toppled palaces, though she has no throne, only a log. Her verb is "resumes," not "begins." Life here has been paused rather than created, and the cat, the sap and the ants are all continuing something.
The poem's significance lies in this combination of modesty and ambition. It gives rain a subject usually associated with gloom, a grey March day, and treats it as a liberating force. It never lectures, and there is no "I" interpreting events, only an observer whose attention turns outward and downward. It ends on an insect rather than a flourish, trusting slow, hidden processes more than spectacle. A reader finishes it listening for the downspouts, and for the small things moving underneath.
