Tropical Depression TWO Has FormedJuly 21st, 2014 at 2:47 pm by Tiffany Savona WAVY under Weather
There was a big afternoon update sent out by National Hurricane Center. We are watching an area of showers and thunderstorms located across the Central Atlantic.
There was only a 10% chance of development last night, so that is why I didn’t talk about it. Now…since the disturbance has become more organized, the National Hurricane Center is giving it a 70% chance of developing into a tropical system over the next 48 hours. Satellite data has shown that the circulation has become more defined and the National Hurricane Center is saying that there is a small area of winds up to tropical storm force. We could see a depression or tropical storm develop at any time if the winds increase or if the storm becomes more organized. The next name on the list is Bertha. This disturbance is currently moving WNW at 15-20mph, heading for the Lesser Antilles. Environmental conditions are favorable for development now, since the wind shear is low. But as this disturbance moves westward, it should encounter more wind shear, which would help to weaken the system.
Here are some computer model runs showing a preliminary track of this disturbance. Keep in mind that these track forecasts are extremely preliminary because this system hasn’t formed yet. I’m showing you this graphic to show the general westward movement of the system. Whether this develops into a tropical system or not, folks across the Lesser Antilles need to monitor this disturbance over the next few days.
I will have a full update coming up on WAVY News 10 at 4 PM and Chief Meteorologist Don Slater will have more information on WAVY News 10 at 5 PM, 5:30 PM, 6 PM and 11 PM. Stay tuned!
NEW UPDATE: Tropical Depression TWO has formed in the Central Atlantic with maximum sustained winds of 35mph. The latest track from the National Hurricane Center has the depression moving westward toward the Lesser Antilles by the end of the week. The depression will be moving into an unfavorable environment (increasing wind shear), not conducive for strengthening over the next few days. There is a chance that Tropical Depression TWO could weaken to an area of low pressure by the end of the week across the Atlantic. Stay tuned for updates!
