There is One Tropical Cyclone in the Atlantic Basin.
Tropical Storm Chantal is located 55 miles NW of St. Lucia and 410 mi SE of San Juan, Puerto Rico and is centered at 14.4N & 61.5W. Max sustained winds are 60mph. Min central Pressure 1006mb (29.71") and Andrea is moving WNW (295) at 29mph.
A Hurricane Watch is in effect for Barahona to Samana, Dominican Republic.
Tropical Storm Warning is in effect for; Dominica, St. Lucia, Martinique, Guadeloupe, Puerto Rico, ...Dominican Republic & North Coast of Haiti from Le Mole St. Nicholas, Eastward.
Tropical Storm Watch is in effect for; U.S. Virgin Islands, Vieques & Culebra, Haiti from Le Mole ...St. Nicholas, South to the border of Dominican Republic, Turks & Caicos, Southeastern Bahamas.
After Satellite analysis, T.S. Chantal is holding together. However, the storm is not showing a strong circulation. This is due mainly to the extreme forward speed of the T.S. Satellite presentation does not show a very healthy structure. Radar data shows the strong and well defined center of Chantal continuing to move rapidly to the West. Since the last Hurricane Hunters' flight the pressure has leveled off to about 1006mb. The environment ahead of Chantal does not appear to be very conducive for intensification. There is only a slight increase in wind speed forecast before the storm crosses Hispaniola. Upper-level winds are forecast to remain unfavorable over the Bahamas and only small strengthening is anticipated after Chantal crosses Hispaniola. This is in agreement with model guidance.
Chantal is racing toward the WNW and is surprisingly showing a closed circulation. Normally storms do not go this speed at low latitudes. However, this storm is being steered by a strong Easterly flow that is on the Southern edge of a Subtropical ridge over the Western Atlantic Ocean. During the next couple of days, Chantal will go up against some tough conditions. This is why much development and intensification is not expected to be rapid. In fact Chantal is currently expected to remain as a Tropical Storm through the entirety of its lifetime.
Chantal, at this point is not expected to affect Central Louisiana.
Elsewhere, tropical development is not expected during the next 48 hours.
