Hawaiʻi’s Pacific Disaster Center (PDC) and Samoa Launch Resilience-Building Initiative As El Niño-driven drought and shifting weather patterns increase risks to Pacific Island communities from cyclones, fires, flooding, and other hazards, Hawaiʻi and Samoa are joining forces on a National Disaster Preparedness Baseline Assessment (NDPBA) to exchange knowledge and strengthen disaster risk reduction, preparedness, and resilience in Samoa. As forecasters warn that El Niño could reach historic strength this year, the Government of Samoa and the University of Hawaiʻi’s Pacific Disaster Center (PDC) launched a yearlong assessment on October 14, 2026, to evaluate the island nation’s disaster risk down to the village level. Led by Samoa’s Disaster Management Office (DMO) under the Ministry of Natural Resources and Environment (MNRE), with support from the U.S. Embassy in Apia, the NDPBA kickoff drew more than 60 participants from across sectors. “The National Disaster Preparedness Baseline Assessment provides an opportunity to bring together national data, technical assessments, institutional knowledge, and stakeholder perspectives to develop a clearer picture of our country’s disaster risk and preparedness,” said Afioga Suʻemalo Talie Foliga, Acting Chief Executive Officer of Samoa’s MNRE. “I would like to acknowledge and thank the United States through its embassy here in Samoa, as well as the team from the Pacific Disaster Center for their immense support and continued partnership.” In his opening remarks, U.S. Chargé d’Affaires to Samoa Matthew Younger said, “Today is a monumental step forward in our journey together. We are breaking new ground with this assessment. Resilience is not built overnight, nor is it built by the government alone. It requires data, technology, community-level awareness, and above all, unwavering partnership, which we are here to offer today and to celebrate by launching the National Disaster Preparedness Baseline Assessment. Today, we are equipping Samoa’s villages, disaster managers, and leaders with the precision tools needed to anticipate threats, protect families, and safeguard Samoa’s sustainable future.” PDC’s findings from the assessment will feed directly into DisasterAWARE, the early warning and decision-support platform used by decision-makers across the Pacific to plan, prepare for, and respond to disasters. The approach enables agencies to make immediate use of assessment data during this El Niño season rather than waiting for a final report. Over the next year, the program will produce district-level risk profiles, an analysis of Samoa’s disaster management capabilities, and a five-year plan of action. #Samoa #NDPBA #DisasterAWARE #SaferWorld #EarlyWarningForAll @SamoaMNRE @usembassysamoa @cfedmha

Isaias has intensified into a hurricane in the central Gulf. Isaias is forecast to continue strengthening into a Category 2 hurricane later tonight before reaching the northern Gulf Coast late Friday into early Saturday. A life-threatening storm surge is expected from the Mouth of the Mississippi River to Suwannee, Florida. Damaging hurricane force-winds are expected over portions of the Florida Panhandle, southern Alabama, and southern Mississippi where a Hurricane Warning is in effect. Damaging wind gusts are possible over much of central and northern Alabama and portions of western and northern Georgia, especially in areas of higher terrain. Isaias will bring heavy rainfall to the central U.S. Gulf coast and much of the Southeast Friday into the weekend. Considerable flash and urban flooding, along with significant river flooding, will be possible.

Tropical Storm Isaias is currently located in the southern Gulf near the Yucatan of Mexico. Isaias is forecast to rapidly strengthen over the next few days into a Category 2 hurricane before reaching the northern Gulf Coast by the end of week. There is a high risk of dangerous wind and storm surge impacts along portions of the northern Gulf Coast from Louisiana to the Florida Panhandle. Hurricane and Storm Surge Watches have been issued for portions of the northern Gulf coast. Tropical Storm Isaias will bring heavy rainfall to the central U.S. Gulf coast and much of the Southeast Friday into the weekend. Flash and urban flooding, along with isolated river flooding, will be possible.

Sending aloha and a big mahalo (thank you) to our long-time partners at the Philippines Office of Civil Defense (OCD)! The team was excited to be back in Manila recently to upgrade PhilAWARE and provide advanced administration training. We also commend OCD for its continued commitment to leveraging the latest technology and data to strengthen early warning, preparedness, and resilience across the region. PhilAWARE serves as a mission-critical tool within OCD's Emergency Operations Center (EOC) for hazard early warning and decision support. These enhancements and training efforts reflect our ongoing collaboration with OCD and help ensure continued access to real-time situational awareness, advanced analytics, hazard information and alerts, and actionable risk insights. Together, these capabilities support informed decision-making, resource prioritization, and coordinated disaster planning and response when it matters most. PhilAWARE is part of PDC’s advanced DisasterAWARE ecosystem and a custom version created for the Philippines. Learn more!

A powerful Nor’easter will impact the Eastern United States this weekend. A strong coastal low over western Atlantic will continue to intensify by late week and will bring strong onshore flow across the Mid-Atlantic northward into the New England by the weekend. Rain will become heavier and more persistent by late Friday into early Saturday. Several days of rainfall could produce locally high rainfall totals, particularly across southern New England and eastern Massachusetts. Impacts will include wind gusts will be in excess of 45 mph, moderate to major coastal flooding, high surf, rip currents, and beach erosion.

As of 11:00 AM HST, Hurricane Lowell remains a powerful Category 3 hurricane, with maximum sustained winds of 120 mph, located approximately 545 miles south-southwest of Līhuʻe and moving north at approximately 6 mph. PDC wind impacts and storm surge estimates are below. Lowell is expected to remain a hurricane as it passes just west of the main Hawaiian Islands, with its center forecast to pass just west of Kauaʻi County late Monday into early Tuesday. Tropical-storm-force winds extend up to 175 miles from the center, allowing impacts to occur well away from the storm's core. A Tropical Storm Warning remains in effect for Kauaʻi County, with hurricane-force wind gusts possible over elevated terrain. Gradual weakening is forecast to begin tonight. Potentially significant impacts include heavy rainfall and flash flooding, dangerous surf and coastal flooding, and tropical-storm-force winds, particularly across Kauaʻi and Niʻihau Monday through Tuesday morning. Kauaʻi could receive 6–10 inches of rainfall, with isolated totals up to 14 inches, with flash flooding and mudslides possible. Storm surge of 1–3 feet is possible in Kauaʻi County, and life-threatening surf and rip current conditions are expected across many of the Hawaiian Islands during the next several days.
