SUMMARY OF 400 PM CDT...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...19.6N 100.1W ABOUT 65 MI...105 KM WNW OF CIUDAD DE MEXICO MAXIMUM SUSTAINED WINDS...25 MPH...35 KM/H PRESENT MOVEMENT...W OR 260 DEGREES AT 13 MPH...20 KM/H MINIMUM CENTRAL PRESSURE...1002 MB...29.59 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: The government of Mexico has discontinued all warnings for the coast of Mexico. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 400 PM CDT (2100 UTC), the remnants of Grace were located near latitude 19.6 North, longitude 100.1 West. The remnants are moving toward the west near 13 mph (20 km/h) and this general motion is expected to continue tonight. Maximum sustained winds are near 25 mph (35 km/h) with higher gusts. Although Grace has dissipated, its remnants will likely move into the eastern North Pacific by Sunday afternoon, where it is likely to develop into a new tropical cyclone next week. The estimated minimum central pressure is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Grace can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2, WMO header WTNT42 KNHC and on the web at www.hurricanes.gov/graphics_at2.shtml?key_messages. RAINFALL: The remnants of Grace will be capable of producing an additional 1 to 3 inches of rain with isolated maximum amounts of around 5 inches through tonight across portions of central Mexico, including Ciudad de Mexico. The lingering heavy rainfall may lead to additional areas of flash and urban flooding, along with mudslides, through tonight. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system. $$ Forecaster Pasch
Public Advisory not available for this storm.
000 WTNT42 KNHC 212045 TCDAT2 Remnants Of Grace Discussion Number 34 NWS National Hurricane Center Miami FL AL072021 400 PM CDT Sat Aug 21 2021 The mountainous terrain of Mexico has taken its toll on Grace. Surface observations and high-resolution visible satellite images indicate that the system no longer has a definite surface circulation, and Grace has degenerated into a trough to the west of Mexico City. Therefore, this is the last advisory on this system. Although the surface center has dissipated, the mid-tropospheric remnants of Grace are expected to continue westward, and to emerge into the eastern Pacific Ocean by late Sunday. There is high likelihood that this will lead to the formation of a new tropical cyclone over that basin by early next week. For additional information on this possibility, see the eastern North Pacific Tropical Weather Outlook under AWIPS header MIATWOEP, WMO header ABPZ20 KNHC and on the web at hurricanes.gov. Key Messages: 1. Through tonight, lingering heavy rainfall from the remnants of Grace may result in additional areas of flash and urban flooding, along with mudslides, over central Mexico.
