Meanwhile, the JTWC estimated maximum intensity of . With maximum intensity, Ike made landfall on the northeastern tip of Mindanao at around 14:00 UTC on September 1, taking 30 hours to track across the southern extent of the Philippines. The cyclone emerged into the South China Sea on September 3, but due to land interaction, both the JTWC and JMA reported that Ike had weakened to a tropical storm upon its emergence. The storm tracked northwestward across the South China Sea over the next few days. Ike regained its former typhoon classification on September 3, according to the JTWC, and on September 4, according to the JMA. Several hours later, data from a Hurricane Hunter aircraft indicated that Ike had developed a wide eye. The JMA estimated that it reached a secondary peak intensity on September 4 with winds of and a pressure of 955 mbar (hPa; 28.20 inHg), only slightly weaker than its peak strength while the JTWC estimated a secondary peak of . The combination of increased wind shear induced by a trough passing to the storm's north and the typhoon's proximity to land caused Ike to weaken. The storm made a September 5 landfall on Hainan as a minimal typhoon. The storm continued to weaken after crossing Hainan, with both the JTWC and JMA estimating that it moved into the Chinese mainland as a tropical storm while it was located southeast of Nanning. Thereafter, Ike quickly weakened inland and dissipated on September 6. Preparations Prior to the typhoon's first landfall, a typhoon warning was issued by the Manila Weather Bureau for the Philippine provinces of Surigao del Norte, Agusan, Leyte, Samar, Camiguin, Bohol, Cebu, Misamis Oriental, and Negros. Local authorities warned at risk residents via radio to flee to higher ground due to the threat of destructive storm surge. Although no mandatory evacuation was in effect, local radio stations broadcast appeals for evacuation every 30 minutes under the direction of the Manila Weather Bureau. When Ike began to turn towards the northwest on September 3, typhoon warnings were issued for coastal areas between Hong Kong and Beihai. Hundreds of cargo ships left port to escape the typhoon.
