Super Typhoon Sinlaku Threatens Saipan and Tinian with Catastrophic Winds and Flooding

Super Typhoon Sinlaku is rapidly approaching Saipan and Tinian, bringing with it the threat of destructive typhoon-force winds, life-threatening coastal flooding, and torrential rainfall. The storm's eyewall is nearing the islands, with dangerous conditions already impacting parts of the Marianas. Residents are urged to take immediate safety precautions.

Key Takeaways

  • Super Typhoon Sinlaku is nearing Saipan and Tinian with maximum sustained winds of 250 km/h (155 mph).
  • Destructive winds, significant coastal flooding, and heavy rainfall are expected.
  • Typhoon warnings are in effect for several islands, including Saipan and Tinian.
  • Residents are advised to seek shelter and avoid coastal areas and flooded roads.

Storm's Imminent Arrival

As of Tuesday afternoon local time, the center of Super Typhoon Sinlaku was positioned just southeast of Saipan and Tinian. The storm is moving northwest at approximately 14 km/h (9 mph). Forecasters indicate a high probability of the storm's center passing directly over or very near Tinian and Saipan Tuesday night. Typhoon warnings remain active for Saipan, Tinian, Rota, Alamagan, Pagan, and Agrihan, while Guam is under a Tropical Storm Warning and Typhoon Watch.

Expected Impacts

Typhoon-force winds, with speeds of at least 119 km/h (74 mph), are anticipated to lash Tinian and Saipan throughout Tuesday afternoon and evening. The intensity and structure of Sinlaku raise concerns about severe wind damage to roofs, power infrastructure, and buildings, potentially leading to prolonged utility outages and hazardous flying debris. A Coastal Flood Warning is in effect until Thursday morning for Guam, Rota, Tinian, and Saipan, with breaking waves expected to reach 6-9 meters (20-30 feet). Significant coastal inundation of 1.5-2.4 meters (5-8 feet) is likely, with wave and wind-driven surf potentially pushing water 3-4.5 meters (10-15 feet) above normal levels along windward shores. Numerous roads may become impassable, and low-lying homes, businesses, and critical infrastructure could be submerged. Shoreline erosion is also a significant concern.

Heavy Rainfall and Flooding

Heavy rain and flash flooding are projected across the Marianas through Wednesday, April 15. Rainfall totals could reach 380-635 mm (15-25 inches) near the storm's center, with Tinian and Saipan expected to bear the brunt of the downpour. Rota could see 250-510 mm (10-20 inches), while Guam is forecast to receive 150-300 mm (6-12 inches), with isolated higher amounts possible. A Flash Flood Warning is already in effect for Guam due to recent heavy rainfall, with additional intense downpours expected. Flooding is anticipated in various locations, including roads, streams, urban areas, and low-lying regions.

Safety Recommendations

Residents in affected areas are strongly advised to remain in reinforced shelters and avoid all non-essential travel. It is crucial to stay indoors during high winds, steer clear of all coastal areas due to the life-threatening surf, and refrain from walking or driving through flooded roads. Residents of Guam are instructed to remain sheltered until an official all-clear is issued by local authorities.
