The difference between tropical storm types and how they’re defined
[RELATED: Tropical disturbance could get hurricane season off to an early start]Unsure if it’s a storm or disturbance, or don’t understand the difference either way? Here’s how it breaks down:A tropical cyclone with sustained surface winds from 39 mph (63 km/hr) to 73 mph (118 km/hr) is categorized as a tropical storm. In September 2019, Tropical Storm Imelda caused major flooding throughout Houston, pouring more than two feet of water over some areas. Finally, a tropical disturbance is defined as a discrete tropical weather system of apparently organized thunderstorms. A tropical disturbance also is not associated with a front and maintains its identity for 24 hours or more.
The difference between Hurricane wind scales and what measure of damage to expect in each category
Here are Hurricane categories and wind scales explained:Category 1 Hurricane: Winds 74-95 mphNo real damage to building structures. Category 2 Hurricane: Winds 96-110 mphSome roofing material, door and window damage of buildings. Category 3 Hurricane: Winds 111-129 mphSome structural damage to small residences and utility buildings with a minor amount of curtainwall failures. Damage to shrubbery and trees, with foliage blown off trees and large trees blown down. Category 4 Hurricane: Winds 130-156 mphMore extensive curtainwall failures with some complete roof structure failures on small residences.
Understanding how tides change during storms
As hurricane season approaches, here’s what to know about tide levels and how they change during storms. Typically, a location will observe two high tides and two low tides within a day. Normal tide (KPRC)A storm surge is an abnormal rise in sea level accompanying a hurricane or other intense storm, caused by wind blowing seawater onshore. Storm surge is usually estimated by subtracting the normal or astronomic high tide from the observed storm tide. Lastly, a storm tide is the actual level of seawater resulting from the astronomic tide combined with the storm surge.
Flash Flood vs. Flood: How its defined and what you need to know
Flash flooding usually happens within minutes to several hours after a heavy rainfall event. Flash Flood WatchAn announcement issued when conditions are favorable for flash flooding. It does not mean that flash flooding will occur, but it is possible. Flash Flood WarningA warning issued when flash flooding is imminent or occurring. Flood WarningA warning issued when flooding is imminent or occurring.

How coronavirus is affecting the weather forecast
HOUSTON Ive written before about the role of airplanes taking and reporting weather observations as they ascend and descend, as well as at flight altitude. Known as the AMDAR program, these commercial aircraft flights traditionally produce 700,000 observations a day (temperature, humidity, and wind). With stay home orders around the globe, there are weather offices with no weather person to physically read and report the data! In addition, the WMO notes that over time even automatic stations will need repair and calibration, so we may see more data dropping out in the next weeks or months. Still, and thankfully, there are a LOT of ways to observe the weather these days.
