As Tropical Storm Harvey pummels the Gulf Coast — and parts of the Texas Gulf Coast, specifically — with record-shattering rainfall, New York is springing into action to help those who need help.

Charities nationwide, such as the American Red Cross and the Salvation Army, are soliciting volunteer assistance and donations.

A Muslim community center, for example, on 89th Ave. near Merrick Boulevard in Jamaica, Queens, is looking to raise about $100,000 to provide bottled water and hygiene kits to those Harvey has walloped.

People are advised to research a charity to make sure their contributions will reach those in need before donating.

New York City and New York State sent relief aid Sunday to help Texas and Louisiana as the storm drenches the states.

More than 100 city emergency workers left for Texas to aid rescue efforts in Houston, and Gov. Andrew Cuomo sent 100 Air National Guardsmen to the region.

About a dozen members of the Red Cross Disaster Assistance Response Team (DART) left New York City on Sunday to travel to Texas.

The group of retired and active FDNY firefighters is expected to provide shelter, serve meals, and distribute relief items in the state's hard-hit communities.

"Whether it's water or blankets or cleaning equipment, whatever the need may be, we'll deliver that," said Lt. George Diaz, a city firefighter and member of DART.

"We'll assess the damage, bring that intel back to headquarters, and then that's distributed to all the other agencies that need to get that information, whether it's the National Guard to get people out, or FEMA to get assistance in," Diaz continued.

The group expects to stay for about three weeks.

Harvey is bringing Houston "catastrophic flooding," as the National Weather Service describes. The country's fourth-largest city has already seen more than 30 inches of rain, and at least five people in the city are dead — a total that is expected to rise once the water recedes.

Thousands of Houston residents have been forced to flee their homes due to rising flood waters. Some parts of the city are expected to receive a record 50 inches of rain.

Officials have issued Flash Flood, Flood, and Tropical Storm Warnings for much of Central and South Texas.

The tropical storm, which had made landfall in Texas on Friday night as a Category 4 Hurricane, continued weakening Sunday with respect to max winds, but it remains a catastrophic, life-threatening flood event.

The catastrophic flooding in the greater Houston area at this time is due to storm training and ample moisture associated with intense rain bands.

Texas Gov. Greg Abbott is urging people to follow local warnings and take the flooding threat seriously.

"What we strongly urge is for all local residents to listen to all warnings from local officials, to heed those warnings. Do not get out onto the road," Abbott said on CNN on Sunday. "Make a plan where you can elevate in your own home or find a place of safety."

President Trump is set to travel to the storm-ravaged state Tuesday.

He is currently monitoring the situation from Maryland's Camp David, and on Twitter he has praised federal, state, and local government response to the storm.

Many Central Texas counties remain under various tropical weather alerts. A Flash Flood Watch is in effect for much of the area until at least Tuesday evening.

The National Hurricane Center on Sunday night offered no promises of relief from the epic rains unleashed on Southeast Texas.

In its 7 p.m. CDT advisory, center forecasters located the center of the storm 10 miles northeast of Victoria, Texas, or about 120 miles southwest of Houston. That center was inching to the southeast at 3 mph with sustained winds of up to 40 mph.

The forecasters said "little change in strength is forecast during the next 24 hours.'' In fact, "some slight re-strengthening is possible after the center moves off the coast on Monday night and Tuesday.''

The storm is expected to rain an additional 15 to 25 inches through Friday over the upper Texas Gulf Coast and into southwestern Louisiana. Isolated storm totals may reach 50 inches over that area, including the Houston-Galveston area.
