<p>Live radar from F5Weather</a></div>

Our radar is based off of US NEXRAD and Canadian weather radar sites through the quality controlled MRMS system. It compiles various sources for radar data and filters out erroneous returns such as sun spikes and ground clutter. We then colorize the precipitation based on our methods for determining precipitation type. Rain is in shades of green, mixed precipitation and freezing rain in shades of pink and snow is in shades of blue.

<p>Live satellite from F5Weather</a></div>

Our satellite is from the GOES-16. It is color enhanced by using a geocolor terrain background during the day and black marble city lights at night. The daytime satellite data is Visible satellite imagery, and nighttime uses Infrared bands. The bluish clouds are fog and low cloud. The whiteest clouds are the coldest, highest cloud tops.

Current surface weather map around New Castle County, DE

This surface map is from the HRRR computer model. It is a 1-hour forecast, updated hourly, which is a good estimate of the current surface conditions. This map shows the current high and low pressure centers, pressure isobar contours, wind streamlines and thickness contours. It also shows the currently depicted preciptiation estimates, although this should not be a substitute for actual live radar. The purple dashed contour is the 5400m thickness line, which is often a good proxy for the rain/snow line.

<p>Hurricane Tracking from F5Weather</a></div>

Our hurricane tracking map monitors for any current or forecast tropical disturbances in the Atlantic. (See our Pacific Hurricane Tracker) Various hurricane models will draw a 'spaghetti plot' in the Atlantic Basin when a disturbance is forecast or exists, showing the system's forecast track. Once a storm has developed, the National Hurricane Center will forecast their official track. This will show up on the map along with the storm's current intensity, track and name. We will also plot some of the storm's vitals and of course the spaghetti plots from the models along with the NHC forecast track will give you an idea of where it's heading, and its forecast intensity with time.

Climate Summary

North Star, Delaware has a humid subtropical climate, with hot, humid summers and mild winters. The average annual temperature is 54.8°F (12.7°C). The warmest month is July, with an average temperature of 76.0°F (24.4°C), and the coldest month is January, with an average temperature of 33.6°F (0.9°C). The average annual precipitation is 42.94 inches (1091 mm), and the average number of days with precipitation is 116. The average annual snowfall is 12.5 inches (32 cm).

The climate of North Star, Delaware is influenced by its location on the Atlantic coast. The Atlantic Ocean helps to moderate the temperature, keeping it cooler in the summer and warmer in the winter. The prevailing wind direction is from the west, which brings warm, moist air from the Gulf of Mexico. This air mass helps to create the humid subtropical climate of North Star, Delaware.

The climate of North Star, Delaware is also influenced by its elevation. North Star is located at an elevation of 10 feet (3 meters) above sea level. This low elevation makes it susceptible to flooding from hurricanes and other coastal storms.

The climate of North Star, Delaware is changing. The average annual temperature has increased by 1.5°F (0.8°C) since the late 19th century. The average annual precipitation has also increased, by about 5 inches (13 cm) since the late 19th century. These changes are consistent with the global trend of climate change.

The changing climate is having a number of impacts on North Star, Delaware. The warmer temperatures are causing the growing season to become longer, and the increased precipitation is leading to more flooding. These changes are also having a negative impact on the local wildlife.

The people of North Star, Delaware are taking steps to adapt to the changing climate. They are building seawalls and levees to protect themselves from flooding, and they are planting trees and other vegetation to help absorb stormwater. They are also working to reduce their greenhouse gas emissions, which are contributing to climate change.
