1958East Pacific未命名Hurricane
● Data reliability: Generally reliable——Aircraft entered typhoons for in situ measurements, but satellites were not yet widespread: tracks are generally accurate, while intensities may be biased, with weaker cyclones potentially going unrecorded from 1950 until the advent of satellite coverage.
未命名 at 1958-07-21 20:00:00 (BeijingTime) 在East Pacific首次被记录, peak intensity 为Cat 1 Hurricane, max wind 约 38.6 m/s (1 分钟平均) , at 1958-07-25 20:00:00前后结束, total 记录 17 track points (6 h一个) .

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1958203N19235 / EP041958. This area has no official Chinese name, so the original English name is used. Intensity categories follow the classifications of local agencies in the area where the system occurred, converted from 1-min sustained wind using the WMO factor, for reference only.
