Tropical Depression Eight Forecast Discussion Number 3

2020-07-23 16:50:23| National Hurricane Center (Atlantic)

Issued at 1000 AM CDT Thu Jul 23 2020 000 WTNT43 KNHC 231450 TCDAT3 Tropical Depression Eight Discussion Number 3 NWS National Hurricane Center Miami FL AL082020 1000 AM CDT Thu Jul 23 2020 Satellite imagery indicates that the depression is getting better organized, with a better-defined center located near the northeastern end of a broadly curved convective band. Satellite intensity estimates from TAFB and SAB have increased to 30 kt, and that will be the initial intensity for this advisory. An Air Force Reserve Hurricane Hunter aircraft is currently enroute to investigate the depression. The initial motion is west-northwestward or 285/8 kt. A mid-level ridge over the central United States is the predominant steering influence, and the global models forecast this ridge to build during the several days. This should cause the depression to turn more westward by 48-60 h and south of west after about 72 h. The track guidance is in good agreement with that scenario, and the new NHC forecast track, which has only minor adjustments from the previous track, lies near the various consensus models. The new forecast track has the center making landfall along the Texas coast between 48-60 h. The depression is in an environment of light shear and over warm sea surface temperatures, so at least slow strengthening is expected until landfall. The new intensity forecast, which lies a little below the intensity consensus, now calls for a peak intensity of 45 kt before landfall. Data from the Hurricane Hunter will give more details on whether the structure of the cyclone has improved or not, which will be incorporated into the next forecast cycle. Key Messages 1. The depression is expected to strengthen and it could bring tropical-storm-force winds to portions of the Texas coast, where a tropical storm watch is in effect. 2. The depression is expected to produce heavy rains along the Gulf Coast from Louisiana to the Lower Texas Coast. These rains could result in flash flooding and minor river flooding.

Hurricane Douglas Forecast Discussion Number 13

2020-07-23 16:47:23| National Hurricane Center (East Pacific)

Issued at 500 AM HST Thu Jul 23 2020 000 WTPZ43 KNHC 231447 TCDEP3 Hurricane Douglas Discussion Number 13 NWS National Hurricane Center Miami FL EP082020 500 AM HST Thu Jul 23 2020 The intensity of Douglas has leveled off in the overnight hours with the eyewall convection weakening, but the eye temperatures becoming a lot warmer, suggesting that the system has become a little more steady state. The wind speed is kept at 105 kt, which nearly matches the latest CIMSS satellite consensus (SATCON). The cyclone has less than a day over warm water left to intensify before it encounters SSTs less than 26C. Douglas should only slowly weaken thereafter during the next few days due to the cooler waters along the predicted track since the vertical shear should remain low through Saturday. As the cyclone approaches the Hawaiian Islands on Sunday, while the SSTs increase, so does the shear, and thus a continued weakening is forecast. Model guidance is consistent from the last forecast, and no significant changes were made to the NHC wind speed prediction. Douglas has been moving a little faster to the west-northwest, or 290/17. A large mid-level ridge over the eastern and central Pacific should continue to steer the hurricane on this general course and speed for the next couple of days, with some deceleration and a westward turn by late in the weekend. While the guidance remains in very good agreement, the only significant change to note is that this forecast is a bit faster than the previous one, but not as fast as the ECMWF or its ensemble mean. Key Messages: 1. Douglas is expected to move near or over portions of the Hawaiian Islands this weekend, and there is an increasing chance that strong winds, dangerous surf, and heavy rainfall could affect portions of the state beginning on Sunday. Interests on the Hawaiian Islands should continue to monitor the progress of Douglas and the official forecasts as they evolve over the next few days.
