to develop good outflow. As a result, the storm attained typhoon status later that day before strengthening slowed. By June 14, Yunya turned towards the west-northwest in response to a subtropical ridge to the north. Following this turn, the typhoon attained its peak intensity as a Category 3-equivalent typhoon on the Saffir–Simpson scale with winds estimated at . Around the same time, the JMA assessed Yunya to have been slightly weaker, with peak winds estimated at along with a pressure of 950 mbar (hPa; 28.05 inHg). Within hours of reaching its peak strength on June 14, strong wind shear associated with a second subtropical ridge over Asia impacted the typhoon. Due to the system's small size, the shear was able to disrupt the cyclone's core and cause rapid weakening as it approached southern Luzon. Around 00:00 UTC on June 15, Yunya made landfall just north of Dingalan Bay as a minimal typhoon and weakened to a tropical storm shortly thereafter. As the storm moved across Luzon, Mount Pinatubo, a volcano in the Zambales Mountains on the island's western side, was experiencing a major eruption—the second-largest to occur during the 20th century. Due to Yunya's circulation, the massive cloud of ash produced by the eruption was moistened and redistributed over the Philippines instead of blowing out to sea, greatly exacerbating the impact of the event. Later on June 15, Yunya emerged into the South China Sea as a minimal tropical storm. Persistent wind shear prevented the system from strengthening and the storm ultimately degraded into a tropical depression by June 16. Having turned north within a break in the subtropical ridge, Yunya brushed the southern tip of Taiwan late on June 16 before dissipating the following day within the westerlies. Preparations and impact On June 14, the Philippine Atmospheric, Geophysical and Astronomical Services Administration raised storm warnings in advance of Typhoon Yunya for much of Luzon and areas south of Manila. With Mount Pinatubo having already erupted once by this time, there were fears that the storm's heavy rains, combined with ash from the volcano, would create massive lahars capable of burying towns away from Pinatubo. As a result, 60,000 individuals were evacuated. Landslides on June 14 destroyed bridges in Santa Fe and homes in nearby Castillejos were washed away. By June 15, air-borne ash combined with the typhoon's rainfall, resulting in widespread travel disruptions and structural collapses. The mixture also
