The increasing frequency and severity of wildfires in the Western United States demand improved fire response tools. Initial Attack Fire Response within the first few hours of ignition is critical in preventing fires from escalating. WIFIRE Firemap has been instrumental in supporting early fire suppression efforts through real-time fire behavior modeling. However, wildfires often burn for days or weeks, necessitating longer-term predictive capabilities. To address this challenge, we extended Firemap to forecast fire spread from the first few hours to five days. This advancement integrates two long-term fire behavior models, ELMFIRE and GridFire, enabling real-time, data-driven decision support. The enhanced Firemap platform improves strategic wildfire response planning, allowing firefighters and emergency managers to anticipate fire spread on extended timelines. We present how these extensions were used during the Los Angeles firestorms of 2025, demonstrating their potential to mitigate wildfire risks, protect communities, and improve firefighting strategies, and make recommendations for effective use of extended attack tools for decision support.
