Tropical Weather Statement
Issued: 3:52 PM Aug. 4, 2020 – National Weather Service
This product covers Southern New England **Tropical Storm Isaias To Impact Southern New England This Afternoon and Early Tonight** NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - None * CURRENT WATCHES AND WARNINGS: - A Tropical Storm Warning is in effect for northern Connecticut, Massachusetts, and Rhode Island. * STORM INFORMATION: - About 350 miles southwest of Boston MA or about 260 miles southwest of Hartford CT - 39.1N 76.1W - Storm Intensity 70 mph - Movement North-northeast or 20 degrees at 35 mph SITUATION OVERVIEW ------------------ Tropical Storm Isaias is expected to quickly track through southeast New York and western New England this afternoon, before heading into northern New England tonight. Most of the storm's impacts will occur during about a 6 hour period from this afternoon through early tonight. Strong southerly winds gusting to 40 to 60 mph may be capable of downing some trees and power lines. There is also the possibility of a few tornadoes. Rainfall totals of 1 to 3 inches are expected, with the higher totals closer to the Berkshires, where urban or small stream flooding may occur. Rainfall totals will decrease farther east. Much of Rhode Island and eastern Massachusetts should receive less than one inch of rain. Minor coastal flooding will affect south coastal Rhode Island and Massachusetts during high tide early tonight, resulting in inundation of 1 to 2 feet ground level, primarily affecting more vulnerable shore roads and low lying areas. Rough surf and an increased risk of dangerous rip currents will affect south coastal beaches today and Wednesday. POTENTIAL IMPACTS ----------------- * WIND: Protect against dangerous wind having possible significant impacts across southern New England. Potential impacts in this area include: - Several large trees snapped or uprooted. - Scattered power and communications outages. * TORNADOES: Protect against a tornado event having possible limited impacts across Southern New England. Potential impacts include: - A few places may experience tornado damage, along with power and communications disruptions. - Large tree tops and branches snapped off, shallow-rooted trees knocked over, and minor damage to roofs. * FLOODING RAIN: Protect against dangerous rainfall flooding having possible significant impacts across parts of western Massachusetts and northern Connecticut. Potential impacts include: - Small streams, creeks, and ditches may overflow. - Rapid inundation of underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water as storm drains and retention ponds overflow. Driving conditions become hazardous. * SURGE: Minor impacts are anticipated across south coastal Rhode Island and Massachusetts, including the Narragansett Bay shoreline, around the time of high tide tonight which occurs between 930 PM and 10 PM. Inundation of 1 to 2 feet above ground level is possible. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Listen to local official for recommended preparedness actions, including possible evacuation. If ordered to evacuate, do so immediately. * OTHER PREPAREDNESS INFORMATION: Now is the time to complete all preparations to protect life and property in accordance with your emergency plan. Ensure you are in a safe location before the onset of strong winds or possible flooding. Keep cell phones well charged. Cell phone chargers for automobiles can be helpful, but be aware of your risk for deadly carbon monoxide poisoning if your car is left idling in a garage or other poorly ventilated area. Rapidly rising flood waters are deadly. If you are in a flood-prone area, consider moving to higher ground. Never drive through a flooded roadway. Remember, turn around don't drown! If a Tornado Warning is issued for your area, be ready to shelter quickly, preferably away from windows and in an interior room not prone to flooding. If driving, scan the roadside for quick shelter options. If in a place that is vulnerable to high wind, such as near large trees, a manufactured home, upper floors of a high-rise building, or on a boat, consider moving to a safer shelter before the onset of strong winds or flooding. Closely monitor weather.gov, NOAA Weather radio or local news outlets for official storm information. Be ready to adapt to possible changes to the forecast. Ensure you have multiple ways to receive weather warnings. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information on creating an emergency plan see getagameplan.org - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Boston/Norton MA around 6 PM EDT, or sooner if conditions warrant.
