Ice & Heavy Snow Load: How to Prep Ocean County Trees Before the First Winter Storm

Published November 1, 2026 · Ocean County Tree Service

Why ice and snow are a different problem from wind

Most of our storm posts are about wind: saturated sand, tipped root plates and rotten trunks in a nor'easter (see the pitch pine and oak warning signs and the nor'easter tree checklist). Winter adds a second kind of load. Freezing rain coats every twig, and heavy wet snow piles on branches and evergreen foliage. According to Trees and Ice Storms (Hauer et al., USDA Forest Service / University of Illinois), ice accumulation can increase branch weight by a factor of 10 to 100. The weight builds slowly, then limbs fail one after another, often at night, and wind on top of the ice makes it worse.

That changes which trees fail. In an ice storm survey of 10,713 street trees in the Journal of Arboriculture after a severe Illinois ice storm, at least 26% of the city's street trees were damaged, and about 17% of the damaged trees needed immediate removal or repair. The study found that larger trees with broad crowns, fine, twiggy branching and structural weakness took the most damage, while wood strength alone didn't predict which trees broke. In other words, it's the shape and condition of the tree, not how hard the wood is, that matters most under ice.

How often it happens here: shore vs. Pinelands

Ocean County is not ice-storm country the way the Poconos or Sussex County are, but it is not immune. Some numbers to keep in mind:

• Warning threshold: per NWS Mount Holly's winter warning criteria, the Mount Holly office issues an Ice Storm Warning for 0.25 inch (radial) of ice or more in 24 hours across most of its area, and 0.50 inch in the northernmost counties. Any measurable freezing rain triggers at least an advisory.
• Season: an NWS climatology of Mount Holly storm events found ice storm events in the region fall between November and March, with January the busiest month, and that most occur north and west of Philadelphia, likely because milder ocean air moves in over the coastal plain.
• Snow: the Office of the New Jersey State Climatologist (Rutgers) puts average annual snowfall at about 10 to 15 inches in the far south of the state versus 40 to 50 in the north, and says snow can fall from about November 15 to April 15 in southern counties.
• Pinelands nights run colder: the same office notes that sandy Pine Barrens soils lose heat fast on clear nights, so inland areas can be 15 to 20 degrees colder than the nearby bay shore. That's why Jackson, Manchester, Plumsted, Lakehurst and western Lacey and Barnegat often get freezing rain or sticking snow while Seaside, LBI and the bay-front parts of Toms River and Brick get plain rain.

The storm that best shows the local risk is Winter Storm Toby in March 2018. The NJ Board of Public Utilities report on the March 2018 nor'easters says Lacey Township reported 15 inches, the highest snowfall in the state, with gusts of 48 mph at Harvey Cedars. Heavy wet snow and wind caused significant tree-related damage and about 87,000 customers in central and southern New Jersey lost power. Across the three March 2018 nor'easters, the report says most of the damage came from toppled trees and falling branches, typically from trees outside the utilities' trimmed rights-of-way. Those are mostly trees on private property, like the ones in your yard.

Which trees break under ice and snow

Trees and Ice Storms (Hauer et al., USDA Forest Service / University of Illinois) rates the ice storm susceptibility of common trees, based on the authors' research and more than 40 published reports. Here's how the species you see most in Ocean County yards line up:

Ratings from Table 2 of Trees and Ice Storms (adapted from Hauer et al. 1993 and 42 publications). Individual trees vary; structure and decay matter as much as species.

The same publication lists the features that raise any tree's risk: included bark in tight forks, dead or decaying branches, broad or lopsided crowns, lots of fine side branches, and vines growing into the canopy. It also notes that shallow-rooted species such as red oak are more likely to tip in an ice storm when the soil is saturated and unfrozen, while frozen ground greatly reduces tipping. On Ocean County lagoon lots and low, wet ground that stays soft into January, that is worth thinking about.

What to fix in November and December

This is the window to do it. Leaves are off the hardwoods so structure is easy to see, most trees are dormant, and crews aren't yet tied up with emergency calls. In rough order of priority:

1. Remove deadwood over targets. Dead limbs are the first thing ice brings down. Bare, gray branches over the roof, driveway, deck, play area or street should come out now. Trees and Ice Storms (Hauer et al., USDA Forest Service / University of Illinois) says trees with extensive decay and cavities near sidewalks, streets, driveways and buildings should be removed promptly. See tree trimming and dead tree removal.
2. Shorten heavy, overextended limbs, don't strip them. A long horizontal limb over the house with all its foliage at the tip is a lever under ice. The fix is a reduction cut back to a smaller lateral branch to take weight off the end. What you don't want is lion-tailing, stripping out the inner branches so foliage is left only at the ends. Penn State Extension calls lion-tailing and topping signs of poor pruning, and lion-tailing puts even more of the load at the tips. ISA's Pruning Mature Trees brochure says generally no more than 25% of the crown should be removed at once, and less on mature trees.
3. Never top. Topping (cutting big leaders back to stubs) grows a mass of weakly attached sprouts that are exactly what ice snaps off a few winters later. If someone offers to “just take the top off” to make a tall pine safer, get a second opinion.
4. Deal with weak forks on trees you want to keep. Two equal stems with bark pinched in a tight V are the classic ice failure. Options are a reduction cut on one stem, a cable or brace rod, or removal. ISA's Managing Hazards and Risk page says cabling and bracing provide physical support for weak branches and stems but are not guarantees against failure; installed hardware must be inspected regularly and not every weak limb is a candidate. Trees and Ice Storms (Hauer et al., USDA Forest Service / University of Illinois) adds that a main trunk that has already split down its fork normally means removal, and cabling isn't recommended in that case.
5. Clear vines out of the crown. Wild grape, poison ivy and English ivy climbing into a tree add surface area for ice to collect. Cut vines at the base; don't pull them out of the canopy.
6. Tie up arborvitae and multi-stem evergreens. Iowa State University Extension recommends tying vulnerable plants such as arborvitae before a snow or ice storm so they form a cone that sheds snow, using soft fabric strips, nylon hose or bungee cords rather than wire or twine that cuts bark, and removing the ties in spring. This is a quick DIY job for a privacy screen.
7. Look at limbs over your service drop. JCP&L trims along the lines between poles on its own schedule, but FirstEnergy says that for a tree between the pole and your home, the homeowner is responsible for the removal (the utility disconnects service first so it can be done safely). JCP&L says falling trees and branches are the number one cause of its customers' outages and that 86% of its tree-related outages in 2023 came from trees outside its rights-of-way. Don't prune near any wire yourself; see what JCP&L will and won't do and use FirstEnergy's report-a-tree-problem form for lines between poles.

Shore vs. Pinelands: what to prioritize

• Barrier islands and bay-front lots (LBI, Seaside Park, Lavallette, Mantoloking): ice is rarer, but wind plus wet snow on salt-stressed pines and arborvitae screens is the issue. Remove dead black pines and tie screens. Browning evergreens may be winter burn, not death (winter burn & salt, black pine decline).
• Mainland suburbs (Toms River, Brick, Point Pleasant, Stafford): mixed oaks, maples and ornamental pears over houses on small lots. Focus on deadwood, weak pear forks and limbs over roofs and service drops.
• Pinelands and inland towns (Jackson, Manchester, Plumsted, Lacey, Barnegat): colder nights mean more freezing rain and sticking snow, and the dominant trees, pitch pine and black oak, are both rated susceptible. Prioritize tall pines and oaks that can reach the house or driveway, dead tops, and rotted or fire-scarred trunks. Lots inside the Pinelands Area have their own clearing rules (Pinelands rules).

During the storm: what not to do

• Don't knock ice off branches. Iowa State University Extension says beating ice-coated branches with a broom or rake only causes more damage, hot water can injure the plant, and in most cases it's best to let ice melt naturally. Trees and Ice Storms (Hauer et al., USDA Forest Service / University of Illinois) agrees that deliberate removal of ice can do more harm than doing nothing.
• Do brush off loose snow, gently and upward. On shrubs and small evergreens, sweep fresh, wet snow off from below. Never brush downward on bent branches.
• Don't pile shoveled or plowed snow on shrubs or small trees, and keep salted snow off beds.
• Stay out from under loaded trees. Large limbs can fail without warning, and nothing a homeowner can do will save a big ice-loaded tree. Park away from big trees if you can.
• Treat every downed wire as live. Call 911 for danger and JCP&L for downed lines. Keep kids and pets away from limbs touching wires.

After the ice melts

Walk the yard once it is safe. Bent birches, arborvitae and young trees often straighten on their own over weeks; Iowa State University Extension advises patience rather than propping or tying bent branches after the fact. Broken limbs should be cut back cleanly to the branch collar (no stubs), torn bark trimmed only to where it's firmly attached, and branches with cracks running along them near the attachment removed, because Trees and Ice Storms (Hauer et al., USDA Forest Service / University of Illinois) notes those hidden cracks have a high potential to fail later. If a tree lost more than half its crown, or a main fork split, have it assessed before deciding to keep it (save or remove after a storm). For hangers, broken tops and trees on structures, use our emergency tree service request and see storm tree cleanup and tree on the house.

DIY or call a pro?

Ask any company for its NJ Tree Care Operator license number and insurance before it climbs (how to check a NJ tree care license). Pruning usually doesn't need a permit, but removing a tree often does in Ocean and Monmouth County towns: check the town-by-town permit guide and, for budgeting, the tree trimming cost guide. For more storm-season background, see the storm prep guide and nor'easter tree damage.
