WarningDesc:Tropical Storm Warning WarningDate:8:49 PM EDT on September 3, 2010 WarningSum:...Tropical Storm Warning Remains In Effect... ...New information... updated probability...winds and storm surge sections. ...Precautionary/preparedness actions... precautionary/preparedness actions... It is very tempting to head toward the coast to observe the rough seas and stronger winds . This can place you...and others in a life-threatening situation. The arrival of Earl will result in large breaking waves along the coast. These breaking waves will seriously injure you if you are struck...or worse pull you out to sea. Watching from rock walls or jetties is especially dangerous. Wind can increase dramatically and suddenly...placing you at risk of being struck by flying debris. ...Probability of tropical storm/hurricane conditions... there is little chance for hurricane conditions at this time. Also...the chance for tropical storm conditions at this time is up to 63 percent. ...Winds... the latest area forecast is for maximum winds of 25 to 35 mph with gusts to 45 mph. However...as Hurricane Earl approaches... stronger winds are still possible...mainly near the Cape Cod canal. The strongest winds will occur into the predawn hours as Hurricane Earl makes its closest approach to Nantucket. Winds will rapidly diminish by Saturday morning. ...Storm surge and storm tide... a storm surge around 1 foot accompanied the evening high tide along the eastern Massachusetts coast. A surge up to 2 feet is expected later this evening but this will coincide with low tide so coastal flooding not expected. At worst...some splashover is possible from large breakers. ...Inland flooding... a Flash Flood Watch remains in effect for rode island and eastern Massachusetts. See latest forecast for latest information. Listen for possible flood warnings for your location...and be ready to act if flooding rains occur. The heaviest rainfall is expected across southeast Massachusetts...including the cape and islands. In that area... 2 to 4 inches of rain is expected with isolated amounts up to 6 inches. Elsewhere across eastern Massachusetts and Rhode Island...1 to 3 inches of rain is likely. However...there is the possibility that a swath of heavier rain could produce 3 to 5 inches of rain in that same area. Much of this rain may fall in a 6 hour period this evening into tonight...which would be enough to produce urban and poor drainage flooding along with isolated small stream flooding. ...Rip currents... Earl will exit into the Canadian Maritimes Saturday. However the southern New England ocean waters will remain very turbulent into this weekend despite improving weather conditions. Therefore... expect high surf and dangerous rip currents to persist into at least Saturday and then slowly ease Sunday...and especially Monday. Beach-goers should check with local beach patrols and lifeguards before entering the water. Some swimming restrictions are possible Saturday. The most dangerous surf conditions are expected at south and east-facing ocean-exposed beaches.
