WINDS TO HIT 140 MPH AS MAJOR HURRICANE PREDICTS NATIONAL HURRICANE CENTER.
BY: WEATHER TEAM | BocaNewsNow.com
BOCA RATON, FL (BocaNewsNow.com) (Copyright © 2021 MetroDesk Media, LLC) — It is still far too early to know what Hurricane Larry will do or where it will go, but the current path continues to suggest a general direction towards the east coast — and possible the just-battered northeast coast — of the United States.
While several unofficial “spaghetti models’ indicate the storm may turn back towards the east, the storm for now continues west. It is expected to reach “major” status — with winds hitting 140MPH — within days.
Another system is also expected to form over the next few days. Its potential path remains unclear. Marked with the yellow X just of the coast of Africa, the yellow oval indicates where a storm may form, not necessarily a direction of travel.
This is the early morning update from the National Hurricane Center:
Larry continues to gradually become better organized. Satellite
images show a fairly compact central dense overcast feature with an
eye occasionally evident. Beyond the inner core, banding features
are gradually becoming more distinct, especially to the south of the
center. The latest Dvorak classifications at 0600 UTC was 4.5/77 kt
from TAFB and SAB, and based on those estimates and the improving
trend, the initial intensity is nudged upward to 80 kt.
Larry is moving west-northwestward at 17 kt. There has been no
change to the track forecast reasoning. A continued westward to
west-northwestward motion is expected on Friday and through the
weekend as the hurricane remains on the south side of a mid-level
ridge. By early next week, Larry is expected to slow down and turn
northwestward when it reaches the southwestern periphery of the
ridge. The models are in fairly good agreement, and the NHC track
forecast lies near the middle of the guidance envelope. This
forecast is largely an update of the previous one.
The environmental factors appear favorable for steady strengthening
during the next few days with wind shear remaining low and mid-level
moisture fairly high. The only slightly negative factor is
marginally warm 26-27 deg C waters that Larry will be moving over
during the next couple of days, which should prevent rapid
intensification. All of the models are in general agreement that
Larry will become a major hurricane in a day or so with continued
strengthening through day 3, and the NHC intensity forecast follows
suit. Some weakening is shown by the end of the forecast period
when the wind shear could increase a little. This forecast is very
similar to the previous one and lies near the high end of the
guidance envelope. It should be noted that eyewall replacement
cycles are possible, which could cause intensity fluctuations that
are challenging to predict.
The leading swell front from Larry is expected to reach the Lesser
Antilles on Sunday, increasing the risk of life-threatening rip
currents and high surf conditions on those islands early next week.
Large swells are likely to spread to areas surrounding the western
Atlantic later in the week as well.
