SUMMARY OF 300 AM MDT...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...18.8N 109.2W ABOUT 255 MI...405 KM WSW OF CABO CORRIENTES MEXICO ABOUT 285 MI...460 KM S OF THE SOUTHERN TIP OF BAJA CALIFORNIA MAXIMUM SUSTAINED WINDS...80 MPH...130 KM/H PRESENT MOVEMENT...WNW OR 295 DEGREES AT 12 MPH...19 KM/H MINIMUM CENTRAL PRESSURE...989 MB...29.21 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 300 AM MDT (0900 UTC), the center of Hurricane Dora was located near latitude 18.8 North, longitude 109.2 West. Dora is moving toward the west-northwest near 12 mph (19 km/h). This general motion with some decrease in forward speed is expected today and Wednesday, with a turn toward the west expected by Thursday. On the forecast track, the center of Dora is expected to pass over or just north of Socorro Island later today, and remain well south of the Baja California peninsula. Maximum sustained winds have decreased to near 80 mph (130 km/h) with higher gusts. Weakening is expected during the next couple of days, and Dora could become a remnant low by Thursday. Satellite data indicate that Dora is a small tropical cyclone. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds only extend outward up to 45 miles (75 km). The estimated minimum central pressure is 989 mb (29.21 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Dora are affecting portions of the coast of southwest Mexico. These swells are expected to spread northwestward and begin affecting portions of the coast of the southern Baja California peninsula today through Wednesday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 900 AM MDT. $$ Forecaster Blake ]]>

  • Hurricane Dora Forecast Discussion Number 10
    Issued at 300 AM MDT Tue Jun 27 2017 000 WTPZ44 KNHC 270834 TCDEP4 Hurricane Dora Discussion Number 10 NWS National Hurricane Center Miami FL EP042017 300 AM MDT Tue Jun 27 2017 Over the past several hours, the satellite presentation of Dora has degraded with cooling eye temperatures and breaks in the eyewall convection noted in the northwestern quadrant. Dvorak estimates are dropping and support a wind speed of 70 kt for this advisory. Dora is moving into cooler waters and a drier airmass, which should cause steady weakening over the next couple of days. Model guidance has come into better agreement on Dora becoming a tropical storm later today and a tropical depression by Thursday. The NHC intensity prediction is on the low side of the guidance since ASCAT confirmed Dora is a rather small tropical cyclone, and these types of systems are known to disappear rather quickly in the cold eastern Pacific waters. It would not be surprising if Dora dissipated faster than shown below. Dora is moving west-northwestward or 295/10 kt. A large deep-layer ridge to the north of the hurricane should keep it moving on a west-northwestward track during the next 24 to 36 hours. After that time, a weaker and more shallow Dora should turn generally westward in the low-level flow before opening up into a trough by day 4. Guidance has shifted slightly northward during this cycle, perhaps due to a deeper model representation of Dora at the current time. The new NHC track forecast reflects that trend and lies a bit north of the previous one, close to the latest multi-model consensus.
