Tropical Storm Dora Forecast Discussion Number 13

27 Jun 22:36 | Weather

Issued at 900 PM MDT Tue Jun 27 2017 000 WTPZ44 KNHC 280236 TCDEP4 Tropical Storm Dora Discussion Number 13 NWS National Hurricane Center Miami FL EP042017 900 PM MDT Tue Jun 27 2017 Convection associated with Dora has continued to decrease this evening and is now separated from the low-level center. A blend of the various objective and subjective Dvorak intensity estimates yields an initial intensity of 45 kt, which could be generous. The tropical cyclone is forecast to continue moving over decreasing sea surface temperatures which should caused continued weakening, and Dora is forecast to become a remnant low in 12 to 24 hours. Dora has turned more westward since the previous advisory, but the long-term motion is still west-northwestward or 285/11 kt. A west-northwestward to westward motion to the south of a low- to mid-level ridge should continue until dissipation occurs in two to three days. The updated NHC track forecast is close to the previous advisory and lread more »

Hurricane Dora Forecast Discussion Number 9

26 Jun 22:46 | Weather

Issued at 900 PM MDT Mon Jun 26 2017 000 WTPZ44 KNHC 270246 TCDEP4 Hurricane Dora Discussion Number 9 NWS National Hurricane Center Miami FL EP042017 900 PM MDT Mon Jun 26 2017 Dora continues to exhibit a very symmetric cloud pattern with a well-defined 25 to 30 n mi wide eye. The convective cloud tops have gradually warmed today, but subjective Dvorak intensity estimates from TAFB and SAB still support an initial intensity of 80 kt. The hurricane will be moving over cooler waters as it crosses the 26 degree Celsius isotherm very soon. Since the shear is expected to remain quite low throughout the forecast period, this may result in a somewhat slower than typical rate of weakening during the next day or so. After that time, Dora will be moving over waters colder than 24 degrees Celsius which should cause a faster rate of decay. Dora is forecast to become a tropical storm in about 24 hours, and degenerate into a remnant low in 2 to 3 days. The NHC intensity forecasread more »

25 Jun 22:46 | Weather

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 reacread more »
