NWS describes Santa Ana winds as dry, pressure-driven flow from the desert toward the Southern California coast, warming as it descends. They are more common from September through May, without a hard start or end date. Check the current forecast and warnings for your address at NWS San Diego. Use that page for ongoing weather, not as a snapshot of today’s conditions.

Well before a forecast

Walk what you can see from a safe place. Note new hanging wood, a new lean, splits, or a crown that looks different from last season. An old lean is not the same as a new change. If something new appears, talk with a qualified independent professional about whether pruning has a purpose for that tree.

ISA’s guide to pruning mature trees says each cut needs a reason tied to size, species, age, and objective. Structural training on young trees can prevent some later attachment problems. Dead or weakly attached wood can be part of that conversation.

If you’re considering an arborist consultation, ask what the independent professional will inspect. An ISA credential belongs to a person. Check ISA’s credential directory if that person’s credential matters. Don’t assume every referred worker holds it.

Tree trimming and structural pruning are job-specific. Our when to prune trees in San Diego guide can help you plan around species and objective.

UC’s pages on water deficit and excess and irrigation management tie watering to species, season, soil, drainage, and actual root-zone moisture. Hot, sunny, windy, dry air can raise demand. Saturated soil can starve roots of oxygen. Check moisture before you add water. Last-minute watering isn’t storm protection.

Before the winds become hazardous

NWS advises preparing shelter and securing movable outdoor items before winds become hazardous. Charge phones and a weather radio if you have one. If you can reach loose yard items from the ground while staying outside the fall zone, move or secure them now. Leave anything that would put you under a damaged tree. Don’t start new cuts, and don’t get on a ladder, roof, or gutter.

During the wind

Seek a sturdy building or an interior room. Follow official updates from NWS San Diego. Stay away from trees and power lines outdoors. NWS notes that downed wires may be live. Don’t photograph, prune, or water from under the canopy.

After the wind

If someone is hurt or a falling tree threatens life, call 911. Look from a safe place. If a line is down, stay away. Call 911 and SDG&E at 1-800-411-7343. Read SDG&E downed-line guidance. Don’t wait to decide whether the line is live. If a line is still standing and a tree or limb is in it, call SDG&E first. Photos are optional and only from a safe place. Don’t probe trunks or roots.

For a non-utility tree hazard, request a qualified assessment. Purdue Extension treats cables and rods as a supplement for weak branch or stem attachments. They don’t eliminate failure risk, and a crown cable isn’t evidence that roots are sound.

After a storm, signs your tree is dying may be worth a look. Emergency tree service and tree removal are for defined hazards after that safety sequence. Our emergency tree removal in San Diego guide covers the same routing.
