Tropical Storm Edouard Forms In The North Atlantic

Tropical Depression Five has strengthened into Tropical Storm Edouard on Sunday night. It is now the earliest 5th Atlantic named storm formation on record. The current earliest 5th named storm formation record in the Atlantic is Emily on July 12 in 2005.

At 11:00 PM AST, the center of Tropical Storm Edouard was located near latitude 37.2 North, longitude 56.9 West. Edouard is moving toward the northeast near 35 MPH (56 KM/H), and an even faster motion in that general direction is anticipated during the next couple of days.

Maximum sustained winds are near 40 MPH (65 KM/H) with higher gusts. Little significant change in strength is forecast before Edouard is forecast to become post-tropical on Monday.

Tropical-storm-force winds extend outward up to 60 miles (95 KM) from the center. The estimated minimum central pressure is 1008 millibars.

There are no hazards affecting land from this tropical storm.

This system is of no threat to the Windward Islands, including Trinidad and Tobago.

Tropical Storm Edouard Forecast Discussion

Satellite images indicate that the cyclone has become better organized during the past several hours, with a large convective burst causing a better-defined low-level circulation. While the center is now becoming exposed due to southwesterly shear, the maximum winds have almost certainly increased from earlier, so the initial wind speed is set to 35 kt. A recent partial ASCAT pass of at least 30 kt outside the RMW also supports the upgrade to a tropical storm, and the CIMSS satellite consensus (SATCON) is even higher than the analyzed intensity.

Edouard is moving northeastward even faster than before, or 055/30 kt. Model guidance is in fairly good agreement on a quick northeastward or east-northeastward motion for the next couple of days before the system degenerates into a trough. Extratropical transition is anticipated by 24 hours due to forcing from a middle-latitude trough and a frontal boundary. Some minor strengthening of Edouard due to the transition process is possible over the next day or so before the global models show a gradual weakening. The track forecast has been adjusted a bit faster to account for the latest guidance and initial forward speed, and the intensity forecast has also been nudged upward to account for the current wind speed.

Edouard is the earliest known 5th named storm on record for the Atlantic basin in the satellite era (1966-present), breaking the record formerly held by Emily on July 12, 2005.
