2026-08-21 17:45 PM SUMMARY: 10cm Radio Burst Begin Time: 2026 Aug 21 0926 UTC Maximum Time: 2026 Aug 21 0932 UTC End Time: 2026 Aug 21 0934 UTC Peak Flux: 140 sfu Duration: 8 minutes Latest Penticton Noon Flux: 125 sfu Comment: observed by LEA station TROPICAL CYCLONE ADVISORY: ABPW10 PGTW 210600 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH PACIFIC OCEANS/210600Z-220600ZAUG2026// REF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/210151ZAUG2026// REF/B/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/210152ZAUG2026// NARR/REFS A AND B ARE TROPICAL CYCLONE WARNINGS.// RMKS/ 1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: (1) AT 21AUG26 0000Z, TROPICAL STORM 17W (SAUDEL) WAS LOCATED NEAR 14.7N 149.0E, APPROXIMATELY 188 NM EAST OF SAIPAN, AND HAD TRACKED NORTH-NORTHWESTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS GUSTING TO 55 KNOTS. SEE REF A (WTPN31 PGTW 210300) FOR FURTHER DETAILS. (2) AT 21AUG26 0000Z, TROPICAL DEPRESSION 18W (EIGHTEEN) WAS LOCATED NEAR 20.2N 108.6E, APPROXIMATELY 159 NM EAST-SOUTHEAST OF HANOI, VIETNAM, AND HAD TRACKED EAST-NORTHEASTWARD AT 02 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 KNOTS GUSTING TO 40 KNOTS. SEE REF B (WTPN32 PGTW 210300) FOR FURTHER DETAILS. (3) NO OTHER TROPICAL CYCLONES. B. TROPICAL DISTURBANCE SUMMARY: NONE. C. SUBTROPICAL SYSTEM SUMMARY: (1) THE AREA OF CONVECTION (INVEST 96W) PREVIOUSLY LOCATED NEAR 35.6N 160.9E IS NOW LOCATED NEAR 38.7N 158.7E, APPROXIMATELY 809 NM EAST OF MISAWA, JAPAN. THE SYSTEM IS CURRENTLY CLASSIFIED AS A SUBTROPICAL CYCLONE, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL AND MIDLATITUDE CYCLONE FEATURES. ANIMATED ENHANCED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS INVEST 96W WITH A FULLY EXPOSED LOW- LEVEL CIRCULATION CENTER (LLCC) AND ASSOCIATED CONVECTION OVER THE NORTHERN PERIPHERY. A POTENT UPPER-LEVEL LOW PRESENTLY INHIBITS CONVECTIVE ACTIVITY OVER THE CENTER, AND PLENTY OF DRY AIR IS WRAPPING INTO THE CIRCULATION. A 202350 METOP-C ASCAT PASS REVEALED AN ASYMMETRIC, ALMOST FRONT-LIKE, WIND FIELD WITH MAXIMUM 30-35 KT WINDS WITHIN THE SOUTHEASTERN QUADRANT. ENVIRONMENTAL CONDITIONS AROUND THIS SYSTEM REMAIN UNFAVORABLE FOR DEVELOPMENT INTO A TROPICAL CYCLONE DUE TO THE COOL SEA SURFACE TEMPERATURES, SUBSIDENCE INDUCED BY THE UPPER- LEVEL LOW, AND THE SURROUNDING DRY AIR. DETERMINISTIC MODELS SHOW 96W TRANSITING NORTHEASTWARD AND DIMINISHING AS THE UPPER-LEVEL LOW WEAKENS AND THE ENVIRONMENTAL CONDITIONS BECOME MORE HOSTILE WITH TIME. FOR HAZARDS AND WARNINGS, REFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH WINDS AND SEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST AUTHORITY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 33 TO 38 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW. (2) NO OTHER SUBTROPICAL SYSTEMS. 2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: NONE. C. SUBTROPICAL SYSTEM SUMMARY: NONE.// NNNN

1 Rain season in the Philippines: June 1st to Oct 31st.   5 Estimated amount of water needed to replace the water used by plants and evaporation from the past week. (Negative numbers mean amount of water needed, positive numbers mean excess water is present).   6 Air Quality Index is provided by Luftdaten System esp8266 and is updated every 5 mins..   9 Solar Index represents either an absolute scale of solar energy (W/m²) using the station’s recorded maximum or a percentage of computed theoretical solar maximum using the station’s location and time of day. These indices differ most when the sun is low on the horizon. The current scale is shown, and will toggle if it or the icon is clicked.   10 Historical average only to day 21 of just the month of August for this station since 2016.   11 Historical average rain this season to day 21 of August for this station since 2016.
