Tropical Storm Dora Forecast Discussion Number 5

2017-06-26 04:46:41| National Hurricane Center (East Pacific)

Issued at 1000 PM CDT Sun Jun 25 2017 000 WTPZ44 KNHC 260246 TCDEP4 Tropical Storm Dora Discussion Number 5 NWS National Hurricane Center Miami FL EP042017 1000 PM CDT Sun Jun 25 2017 Dora's cloud pattern has continued to quickly improve this evening. Several well-defined spiral bands wrap around the center and the CDO has become more symmetric and expanded since the previous advisory. Recent microwave imagery suggest that an eye feature has formed within the CDO. Subjective Dvorak intensity estimates from TAFB and objective estimates from UW/CIMSS supported an intensity of 55 kt at 0000 UTC, but with the continued improved structure, the initial intensity has been set to 60 kt for this advisory. Dora is forecast to move over warm water and remain within a low shear environment during the next 12 to 24 hours. These conditions should allow for additional intensification and Dora is likely to become a hurricane by early Monday. The tropical cyclone is forecast to reach cooler waters in about a day, which should begin the weakening process. A faster rate of spin down is expected by late Tuesday as Dora moves over even colder waters and into a more stable environment. The NHC intensity forecast is a little above the ICON consensus through 36 hours, and is in best agreement with the LGEM guidance later in the period. Dora is moving west-northwestward or 300/12 kt. A strong mid-level ridge to the north of Dora is expected to steer the tropical cyclone west-northwestward over the next couple of days. After that time, a weaker and more shallow Dora should turn westward. The updated NHC track forecast is similar to the previous advisory and lies a little south of the TVCN model consensus out of respect for the typically reliable ECMWF which is along the southern edge of the guidance envelope. Although Dora is forecast to remain offshore, the outer bands of the tropical cyclone could bring locally heavy rainfall to portions of coastal southwestern Mexico through Monday.

Tropical Storm Dora Public Advisory Number 5

2017-06-26 04:46:09| National Hurricane Center (East Pacific)

Issued at 1000 PM CDT Sun Jun 25 2017 000 WTPZ34 KNHC 260246 TCPEP4 BULLETIN Tropical Storm Dora Advisory Number 5 NWS National Hurricane Center Miami FL EP042017 1000 PM CDT Sun Jun 25 2017 ...DORA QUICKLY STRENGTHENING... ...EXPECTED TO BECOME A HURRICANE SOON... SUMMARY OF 1000 PM CDT...0300 UTC...INFORMATION ----------------------------------------------- LOCATION...16.4N 104.3W ABOUT 180 MI...290 KM S OF MANZANILLO MEXICO ABOUT 290 MI...470 KM SSE OF CABO CORRIENTES MEXICO MAXIMUM SUSTAINED WINDS...70 MPH...110 KM/H PRESENT MOVEMENT...WNW OR 300 DEGREES AT 14 MPH...22 KM/H MINIMUM CENTRAL PRESSURE...996 MB...29.42 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1000 PM CDT (0300 UTC), the center of Tropical Storm Dora was located near latitude 16.4 North, longitude 104.3 West. Dora is moving toward the west-northwest near 14 mph (22 km/h) and this general motion with some decrease in forward speed is expected over the next 48 hours. On the forecast track, the center of Dora is expected to move parallel to but remain offshore of the coast of southwestern Mexico. Maximum sustained winds have increased to near 70 mph (110 km/h) with higher gusts. Additional strengthening is forecast during the next 24 hours and Dora is expected to become a hurricane by early Monday. Weakening is forecast to begin Monday night or Tuesday. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The estimated minimum central pressure is 996 mb (29.42 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Dora is expected to produce rain accumulations of 1 to 3 inches along coastal sections of the Mexican states of Guerrero and Michoacan through Monday. 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 on Tuesday. 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 400 AM CDT. $$ Forecaster Brown
