This has had the following effect on the charts listed below. Charts not listed are not affected. Chart V-B. Snow depth is now measured at 7 a.m. EST instead of 7:30. Charts IX and X. Circle indicates cyclone and anticyclone positions at 7 a.m. EST instead of 7:30. Chart XI. Average sea-level pressure is computed from the 7 a.m. and p.m. EST readings instead of 7:30 a.m. and p.m. Charts XII-XVII. All the upper-air charts are now for 1200 GMT instead of 0300 GMT. All winds are based on rawinsonde observations. Use of pibal data has been discontinued in these charts. USCOMM-WB-Asheville - 12/10/57 - 1850 - 452 - Chart I. A.
