Definition

Typhoon Zack — carried in the Philippine record by its PAGASA local name Pepang and designated Tropical Depression 28W — was the late-October 1995 typhoon of the Northwestern Pacific that crossed the central Philippines on October 28, 1995, striking Leyte with 70-knot (130 km/h) sustained winds before intensifying over the Visayan Islands, then explosively deepening over the South China Sea to a 120-knot peak and striking central Vietnam on November 1. (Wikipedia — 1995 Pacific typhoon season, JTWC — 1995 Annual Tropical Cyclone Report) The season record classifies it a “very strong typhoon” of 165 km/h (10-minute winds) and 950 hPa, active October 24 to November 2 across the Caroline Islands, the Philippines, Vietnam, and Cambodia. (Wikipedia — 1995 Pacific typhoon season)

Zack’s Philippine toll made it the first disaster of a brutal fortnight. The JTWC’s report counts “over 110 deaths reported, of which 72 occurred in Negros Occidental, 18 in Cebu, and 20 in Iloilo,” with flooded rivers and capsized boats claiming most of the victims, more than 30,000 homes destroyed or damaged, and Bacolod without power for days — while the Hong Kong Observatory’s report, as the season record summarizes it, put the country’s toll at over 160, and the season’s effects table carries US$90 million in damage and 110 deaths. Five days after Zack’s landfall, Super Typhoon Angela (Rosing) struck on November 2 with 260 km/h winds and nearly 900 deaths, from the same monsoon trough that had spawned Zack.

Examples and Analogies

A storm that grew over the islands: like Sibyl (Mameng) a month earlier, Zack “intensified as it crossed the central Philippines” — the counterintuitive behavior the JTWC’s discussion section examines, a cyclone strengthening while passing through an archipelago of high islands. (JTWC — 1995 Annual Tropical Cyclone Report, Wikipedia — 1995 Pacific typhoon season)
Two ledgers for one typhoon: the Philippine death toll is a case study in disaster accounting — the JTWC’s “over 110 deaths” (72 Negros Occidental, 18 Cebu, 20 Iloilo) against the Hong Kong Observatory’s “over 160” — every figure attributable to its carrier, none a single official count. (JTWC — 1995 Annual Tropical Cyclone Report, Wikipedia — 1995 Pacific typhoon season)
One trough, two disasters: the monsoon trough that produced Yvette and Zack also spun up Angela — Zack crossed the Visayas on October 28, Angela hit Luzon on November 2 — the sequencing that made the season’s Philippine toll cumulative. (Wikipedia — 1995 Pacific typhoon season)

Usage Scenarios

1. Accounting for the 1995 Philippine Toll

Disaster researchers use Zack as the first entry in the 1995 Visayas-Luzon sequence: the JTWC’s provincial breakdown of the dead and its Bacolod and 30,000-home damage figures give the storm’s own ledger, distinct from Angela’s 882-936 deaths and 9.33 billion pesos — two ledgers frequently conflated in retellings. (JTWC — 1995 Annual Tropical Cyclone Report, Wikipedia — 1995 Pacific typhoon season)

2. Sequencing Warnings and Relief in a Cluster Season

Emergency managers read Zack as the test case for back-to-back operations: a Visayas typhoon in late October followed within five days by a Luzon super typhoon, in a basin where an average of 20 cyclones enter the Philippine Area of Responsibility yearly and 8 or 9 cross the country, the July-October peak carrying nearly 70 percent of development. (PAGASA — Tropical Cyclone Information)

3. Cross-Basin Tracking into Vietnam

The storm’s second life over the South China Sea — explosive deepening followed by a 100-kt landfall south of Da Nang — makes it a standard case for warning responsibility passing across national services, from JTWC and PAGASA to Vietnam’s hydrometeorological service. (JTWC — 1995 Annual Tropical Cyclone Report, Wikipedia — 1995 Pacific typhoon season)

Strategies

Track the monsoon trough, not just the storm: the 1995 trough that built Yvette, Zack, and Angela is why forecasters watch the parent system — readiness for one cyclone means readiness for its siblings within the fortnight. (Wikipedia — 1995 Pacific typhoon season)
Prepare for a strengthening landfall: Zack hit Leyte at typhoon strength and was stronger over Panay — island communities on a crossing track face a worsening storm, not a weakening one. (JTWC — 1995 Annual Tropical Cyclone Report)
Attribute every casualty figure: the discipline the season record models — JTWC “over 110,” HKO “over 160,” each named — is the only honest way to carry a toll no single source fixes. (JTWC — 1995 Annual Tropical Cyclone Report, Wikipedia — 1995 Pacific typhoon season)
Treat rivers and boats as the killers: most of Zack’s Philippine victims died from flooded rivers and capsized boats, not wind — the hazard profile that drives inland-flood and small-craft warnings. (JTWC — 1995 Annual Tropical Cyclone Report)

Security and Safety Measures

Classify before you warn: PAGASA’s scale defines a typhoon at maximum winds of 118-184 km/h and a super typhoon at 185 km/h or more — the bands that set the warning vocabulary for Zack’s crossing. (PAGASA — About Tropical Cyclone, Wikipedia — 1995 Pacific typhoon season)
Guard the grid and the sugar lands: Bacolod’s multi-day blackout and the US$2 million in agricultural losses, primarily sugar cane, mark the exposures a Visayas typhoon repeats. (JTWC — 1995 Annual Tropical Cyclone Report)
Expect the second storm: response plans written for Zack were overrun by Angela within a week — the cluster-season reality Philippine relief doctrine now plans around. (Wikipedia — 1995 Pacific typhoon season)
For researchers: carry the local name with its attribution — “Pepang” is documented in the season record’s heading and naming table, not on a current PAGASA primary page — and keep Zack’s deaths separate from Angela’s in every tally. (Wikipedia — 1995 Pacific typhoon season)

Historical Context

Zack was born in the closing weeks of the 1995 season, a slightly below-average year shaped by the developing 1995-96 La Niña. From a near-equatorial trough disturbance near Kosrae on October 21 it organized slowly into Tropical Depression 28W by October 25 and Tropical Storm Zack on the 26th, reaching typhoon strength as it bore down on the Visayas. The crossing of October 28 — Leyte at 70 knots, 90 knots over the Visayas, Panay at 62 — wrote the Philippine record: the JTWC’s “considerable death, destruction, and agricultural losses” centered on Panay and Negros Occidental, the provincial death counts, the destroyed homes, and the Bacolod blackout. (JTWC — 1995 Annual Tropical Cyclone Report, Wikipedia — 1995 Pacific typhoon season)

Over the South China Sea the storm rewrote itself — 45 knots of deepening in 18 hours to a 120-knot peak — before landfall south of Da Nang on November 1 and dissipation over Laos and Thailand, the Vietnamese record adding 27 deaths. In the Philippines the fortnight belongs to the sequence: five days behind Zack came Angela — Rosing — the Category 5-equivalent landfall of November 2 that killed hundreds in Bicol and passed over Metro Manila, closing the season’s Philippine account as this site’s Typhoon Angela entry documents.

Challenges and Controversies

The Casualty Variance

No single Philippine death toll for Zack exists: the JTWC reports over 110 dead with its provincial breakdown, the Hong Kong Observatory over 160, and the season table 110 with US$90 million in damage — a spread carried here attribution by attribution, as the season record itself does. (JTWC — 1995 Annual Tropical Cyclone Report, Wikipedia — 1995 Pacific typhoon season)

Conflation with Angela

Popular summaries regularly merge Zack’s Visayas toll with Angela’s Bicol-Luzon catastrophe five days later, or reverse the order of the storms. The record is unambiguous: Zack crossed on October 28, Angela struck on November 2, and Angela killed the larger number. (Wikipedia — 1995 Pacific typhoon season)

A Local Name Without a Primary Carrier

The PAGASA name “Pepang” is documented by the season record’s own heading and naming table, but the old PAGASA pages that once listed the 1995 destructive-cyclone tables are offline, and no current PAGASA primary page verified this session carries the name — an archival gap noted here rather than filled. (Wikipedia — 1995 Pacific typhoon season)

A Storm Without Its Own Article

The English Wikipedia “Typhoon Zack” is a redirect to the season article, and Wikidata carries no dedicated item for the 1995 storm — so linked-data citations cannot verify the storm itself, only the season that carries its record. (Wikipedia — 1995 Pacific typhoon season)
