Super Typhoon Sinlaku Disrupts Pacific Shipping – How Shippers Can Protect Cargo from Delay Risks

Super Typhoon Sinlaku struck the Mariana Islands this week, bringing powerful winds and heavy rainfall that caused widespread flooding, structural damage, and power outages in Saipan and Tinian. Our thoughts are with the affected communities and local industries as they begin the recovery process.

According to Weathernews AIS tracking data, commercial vessel traffic near Guam dropped significantly during the storm’s peak. Many ships were forced to divert hundreds of nautical miles or hold position in open waters, resulting in delays on transpacific and intra-Asia routes.

Every Extra Day at Sea Increases the Risk of Container Rain

Longer voyages mean more temperature fluctuations inside sealed containers. Daytime tropical heat raises humidity, while cooler nights or shifts into colder waters cause moisture to condense on the steel walls and ceiling, dripping onto the cargo below. This “container rain” effect is worsened by moisture released from wooden pallets, cardboard, textiles, leather, and agricultural products.

When a planned 25-day transit stretches to 40 or 50 days due to storm rerouting and port congestion, the risk of cargo damage rises sharply.

2026 Pacific Storm Season May Bring Added Challenges

NOAA’s latest forecasts indicate a roughly 61% chance of El Niño developing by mid-to-late 2026. This shift could influence storm frequency and intensity across the Pacific, potentially leading to more route diversions and extended transit times for shippers.

Long-Lasting Moisture Protection for Real-World Voyages

Standard desiccants that saturate within the first few days offer little protection when delays occur. Super Dry Desiccants are engineered to keep absorbing moisture throughout the entire journey — even when voyages run much longer than planned.

If your current moisture control strategy is based only on ideal transit times, this could be the year to review it. Preparing for worst-case scenarios helps safeguard your cargo and maintain supply chain reliability.
