How to Clear Leaves From a Storm-Drain Grate Before Fall Rain
Short answer: remove the first layer of leaves by hand, check that the grate and surrounding channel are stable, then use a blower from the upstream side with the air directed away from the opening. Do not force wet leaves into the drain, stand in moving water, or use a blower near exposed electrical equipment. September’s mix of hot weather, falling leaves, and sudden storms makes this a small job worth doing before rain starts.

Why a grate needs a careful cleanup
A storm-drain grate is designed to admit water while keeping larger debris out. If leaves bridge across the top, water can collect on a driveway, walkway, or low part of the yard. A blower can help with loose, dry material, but it should finish the cleanup rather than discover hidden objects. Wet leaves, gravel, sticks, and trash can become projectiles or clog the channel farther downstream.
Walk the area first. Look for loose grate sections, standing water, slippery pavement, low branches, pets, children, and nearby vehicles. If the drain is on a public road, beside a steep drop, or surrounded by floodwater, do not enter the area; contact the responsible public-works department. Never lift a heavy grate without the right tool and help.
A safe sequence for the homeowner
1. Clear the visible layer
Wear gloves and pick up large leaves, twigs, plastic, and stones from the grate surface. Put them in a yard-waste container rather than the opening. Do not pull on cables, pipes, or unfamiliar objects. If the grate is packed with mud or the channel is already backing up, stop and arrange professional or municipal service.
2. Work from the edge
For a private, stable drain, stand on dry ground and keep both feet outside the channel. Use short blower bursts from the clean side toward a collection area. The goal is to move debris into a pile that you can rake or pick up, not to make it disappear into the grate. A low setting gives you more control near landscaping and loose gravel.
3. Check the result without reaching in
After the surface is clear, inspect the openings from above. A small amount of water from a hose can show whether the top grate accepts flow, but do not use a hose during a storm or when the drain is already surcharged. If water remains pooled, if the grate rocks, or if you hear gurgling and see a slow drawdown, report the issue instead of probing the pipe.
4. Keep the next storm easier
Trim or rake back loose leaves near the drain, but preserve rooted plants and soil. Recheck after the first windy day and again before a forecast storm. Do not pile mulch, grass clippings, or compost against the grate. If the drain sits below a tree, a small collection bin or a hand rake kept nearby can make frequent light cleanups safer than waiting for one large blockage.
When a cordless blower is appropriate

The current listing identifies a 40V brushless cordless blower with a Default Title configuration; it is not a substitute for clearing a blocked underground line, moving floodwater, or handling wet compacted material.

Bottom line
Keep leaves out of the drain, work from stable dry ground, and use air only to gather loose debris. If the grate, channel, or water flow looks unsafe, stop and report it. A clear surface helps rain enter the drain, but it cannot correct a damaged grate or blocked underground pipe.
