5:00 PM WEDNESDAY SUMMARY
Location: 16.5°N 73.7°W
Max Wind: 45 MPH

Minimum Pressure: 1012 mb

Chantal continues to lose strength and has been downgraded to a remnant low. The storm still has potential to bring heavy rainfall to Southeast Florida this weekend. Due to the weakening nature of Chantal this will be the last update.

8:00 AM WEDNESDAY SUMMARY
Location: 15.5°N 70.8°W
Max Wind: 45 MPH
Movement: W 29 MPH
Minimum Pressure: 1011mb

Tropical Storm Chantal might be anything but, as of the 8am Update. The official forecast (seen above) has the system remaining at tropical storm strength through tonight, until it's interaction with Haiti, and then calls for it to become a tropical depression as it crosses towards the south side of Cuba.

Tropical storm force winds continue to be felt roughly 90 miles to the north and east of Chantal's center.

That all said, observations from Hurricane Hunter Aircraft and NOAA buoy data suggest that Chantal may no longer have a closed area of circulation. The structure of the storm has become ragged and barely classifies as a tropical storm. Even if Chantal can remain a tropical storm for the next day or so, it will encounter upper level wind shear which should continue to deteriorate the system into a tropical wave.

The official forecast cone of uncertainty continues to shift slightly to the west. Even though this system could be downgraded, gusty winds and heavy rainfall will be in store for Cuba and then eventually Florida by the weekend. Below is the compilation of different computer models used to build the official forecast path (by the National Hurricane Center) and below that is the expected rainfall for the United States for Saturday (7/13) through Monday (7/15).

Max Wind: 65 MPH

Minimum Pressure: 1006 MB

Chantal continues to strengthen with winds increasing to 65 MPH. The storm has a tight center of circulation and is expected to strengthen slightly before reaching Hispaniola.

After Crossing over Hispaniola, Chantal will have weaken slightly and be moving into unfavorable wind conditions. only modest restrengthening is predicted.

10:00AM TUESDAY SUMMARY
Location: 14.4°N 61.9°W
Max Wind: 60 MPH
Movement: WNW 29 MPH
Minimum Pressure: 1006mb

The latest advisory for Tropical Storm Chantal shows the storm has strengthened as winds have increased to 60mph and the pressure has dropped off around 4mb. The storm was crossing around St. Lucia as of the last update.

Tropical storm force winds can be felt 90 miles outward from the center of circulation, mainly to the northeast of the center.

According to the National Hurricane Center, the environment ahead of Chantal is not very favorable for intensification. Winds are only expected to increase slightly before reaching and crossing Hispaniola.

The official forecast cone (shown above) continues to indicate that this will be a tropical storm by the time it nears the Eastern Florida coastline. At that time, the storm's forward movement is expected to slow.

8:00AM TUESDAY SUMMARY
Location: 13.8°N 59.7°W
Max Wind: 50 MPH
Movement: WNW 26 MPH
Minimum Pressure: 1010mb

Not much has changed overnight with T.S. Chantal other than the storms position. Tropical storm force winds are can be felt all around the center of circulation, with the exception of the south side of this storm. Those winds extend about 90 miles outward (and mainly north) of the center of Chantal.

Chantal is expected to impact the Lesser Antilles later today and continue on a relatively unchanged pace towards Hispaniola. Due to moderate wind shear and the storms quick movement, little to no intensification is expect over the next day or so. By the time this storm nears Florida, by the end of the week / weekend, forward movement should slow down due to a trough of low pressure over the Eastern U.S.

While there should be some weakening due to land interaction over the Dominican Republic and Haiti, the official forecast from the National Hurricane Center calls for Chantal to remain a Tropical storm through the 5 day forecast period.

8:00 PM MONDAY SUMMARY
Location: 11.8°N 55.0°W
Max Wind: 50 MPH
