Tropical Storm Karen Forecast Discussion Number 5

5 years 9 months ago
Issued at 500 AM AST Mon Sep 23 2019 000 WTNT42 KNHC 230911 CCA TCDAT2 Tropical Storm Karen Discussion Number 5...Corrected NWS National Hurricane Center Miami FL AL122019 500 AM AST Mon Sep 23 2019 Corrected Key Messages Karen's convective pattern has become quite disheveled looking this morning due to 20-25 kt of northeasterly vertical wind shear. a narrow band of deep convection has recently reformed in the southeastern quadrant, but proximity to dry air has been hindering development and organization of that convection. The initial intensity has been held at 35 kt until the next reconnaissance flight later this morning provides new information on the strength of the cyclone. However, I would not be surprised if Karen has weakened to a tropical depression based on the lack of significant convection. The initial motion is now 320/07 kt. The track guidance remains in excellent agreement that Karen should continue a northwestward motion today toward a break in the subtropical ridge, followed by a northward motion on Tuesday that would take the center of the cyclone near or over Puerto Rico and the U.S. Virgin Islands in about 36 hours. Karen is forecast to emerge over the southwestern Atlantic near 48 hours and then slow down significantly and possibly even stall or loop several hundred nmi north of Puerto Rico on days 4 and 5 as a large ridge builds to the north of the cyclone. The new NHC track forecast is similar to the previous advisory, and lies close to the average of the consensus track models TVCN, NOAA-HCCA, and FSSE. The upper-level winds are expected to remain unfavorable for the next 24 hours or so, and I would not be surprised if Karen weakens to a tropical depression during that time. By 36 hours and beyond, however, upper-level winds are expected to become much less hostile, allowing some modest strengthening to occur. By days 4 and 5, Karen is forecast to move underneath an upper-level anticyclone, which should allow for more significant intensification to occur. The new official intensity forecast is similar to the previous one, and follows the trend of the various intensity consensus models. Key Messages: 1. Heavy rainfall will continue to affect portions of the southern Windward Islands through tonight. 2. Karen is forecast to approach Puerto Rico, and the U.S. and British Virgin Islands on Tuesday, and a tropical storm warning is in effect. Tropical-storm-force winds, heavy rainfall, and flash flooding are possible on these islands.

Tropical Storm Kiko Forecast Discussion Number 44

5 years 9 months ago
Issued at 1100 PM HST Sun Sep 22 2019 000 WTPZ43 KNHC 230859 TCDEP3 Tropical Storm Kiko Discussion Number 44 NWS National Hurricane Center Miami FL EP132019 1100 PM HST Sun Sep 22 2019 GOES-17 enhance infrared imagery and an earlier METOP-A AMSU pass show that resilient Kiko is producing intermittent bursts of deep convection with associated -77C cold cloud tops near the surface center. These convective bursts, based on the TAFB and SAB intensity estimates, are substantial enough to maintain its tropical storm status of 35 kt for this advisory. Both the ECMWF and FV3GFS Decay SHIPS statistical-dynamical intensity models show Kiko briefly re-strengthening as it continues moving over warm SSTs and in a favorable upper-level wind environment. By Tuesday afternoon, increasing southwesterly shear and cooler waters should induce a weakening trend, and Kiko is forecast to become a remnant low in less than 3 days with dissipation occuring by the end of the forecast period. The initial motion is estimated to be west-southwestward, or 255/8 kt, just south of due west. Kiko is expected to turn westward to west-northwestward on Monday, and then northwestward on Tuesday as a high amplitude mid-tropospheric trough cuts off, from the upper-level westerlies, to the northwest of the cyclone. At the 72 hour period, as the cyclone degenerates into a vertically shallow remnant low, Kiko should, once again, turn back toward the southwest within the low-level tradewind flow. The NHC track forecast is close to the previous advisory and based on a blend of the various multi-model consensus aids.

Tropical Storm Jerry Forecast Discussion Number 24

5 years 9 months ago
Issued at 500 AM AST Mon Sep 23 2019 000 WTNT45 KNHC 230854 TCDAT5 Tropical Storm Jerry Discussion Number 24 NWS National Hurricane Center Miami FL AL102019 500 AM AST Mon Sep 23 2019 Overnight the center of Jerry became partially exposed, a result of strong westerly shear. However, a new burst of very deep convection has recently formed and obscured the low-level center again. The initial wind speed is held at 55 kt, which is well supported by earlier ASCAT data, and another reconaissance mission is scheduled for this morning to take a closer look. The current shear is forecast to slightly weaken during the next few days as the storm moves over progressively cooler waters with drier air in the mid-levels. There will also be a mid-latitude trough that will be near Jerry in a day or so, but the evidence is piling up that the trough interaction will be a neutral or negative factor for the storm. The intensity forecast is held almost the same as the previous one, following the corrected- consensus guidance. The cyclone could be close to dissipating around day 5 due to continuation of the shear and cold water if the latest global models are correct, so the forecast is lowered at that time. Jerry is moving north-northwestward at 8 kt, and that general motion should continue for about another day as it remains steered by a mid-level ridge to its northeast. A sharp turn toward the northeast and then the east is forecast after that when the trough reaches the system causing it to become embedded in the mid-latitude westerlies. There are some substantial speed differences in the models, partially due to the aforementioned trough interaction, but most of the models are still in agreement with the above scenario. The new forecast is close to the previous one, adjusted somewhat to the south at longer range. Key Messages: 1. Tropical-storm-force winds are possible on Bermuda by late Tuesday. Large swells are also expected to affect the coast of Bermuda during the next few days. These swells could cause life-threatening rip currents. See products issued by the Bermuda Weather Service for more information.

Tropical Depression Thirteen Forecast Discussion Number 2

5 years 9 months ago
Issued at 500 AM AST Mon Sep 23 2019 000 WTNT43 KNHC 230852 TCDAT3 Tropical Depression Thirteen Discussion Number 2 NWS National Hurricane Center Miami FL AL132019 500 AM AST Mon Sep 23 2019 Infrared and passive microwave satellite imagery indicate that the depression is gradually getting better organized, with upper-level outflow improving in all quadrants. However, the low-level and mid-level circulations do not appear to be vertically aligned quite yet, with the mid-level center displaced a little to the west of the low-level center. As a result, the intensity has been maintained at 30 kt for this advisory. The initial motion is 270/13 kt. A strong deep-layer ridge to the north of the cyclone is expected to steer the system generally westward to west-northwestward for the next 72 hours or so, resulting in the center passing well to the south and southwest of the Cabo Verde Islands today and tonight. On days 4 and 5, a motion toward the northwest is expected as the cyclone begins to move into a weakness in the ridge. The new track guidance remains tightly clustered about the previous forecast track, so no significant changes were required. The cyclone is forecast to remain in light vertical shear conditions throughout the 5-day period. That favorable upper-level flow regime will combine with SSTs near 29 deg C and a moist mid-level environment to allow the cyclone to steadily strengthen into a hurricane by Tuesday and be near major hurricane strength by day 4. The new NHC intensity forecast is just an update of the previous advisory and closely follows the HCCA and IVCN consensus models.
