There is also a probability of precipitation for every location in the United States for every minute for the next two hours. This is also known as a minute-cast. This is also known as a minute-cast. The Weather Channel 's definition may include precipitation amounts below 0.01 inch (0.254 mm) and includes the chance of precipitation 3 hours ...
In 2023, global temperatures were roughly 2.4 degrees F higher than they were in preindustrial times, meaning today’s storms can deliver a stronger punch. Indeed, extreme precipitation events ...
This method has been used for years within National Weather Service forecasts, as a period's chance of rain equals the chance that 0.01 inches (0.25 mm) will fall in any particular spot. [16] In this case, it is known as probability of precipitation. These probabilities can be derived from a deterministic forecast using computer post-processing.
[1] [2] [3] The Weather Channel has been empirically shown, and has also admitted, to having a wet bias in the case of low probability of precipitation (for instance, a 5% probability may be reported as a 20% probability) but not at high probabilities of precipitation (so a 60% probability will be reported as a 60% probability). Some local ...
Time of concentration is a concept used in hydrology to measure the response of a watershed to a rain event. It is defined as the time needed for water to flow from the most remote point in a watershed to the watershed outlet. [1] It is a function of the topography, geology, and land use within the watershed.
Rainfall in these regions averages between 300 and 600 millimeters (11.8 and 23.6 in) per year, with lower amounts across Baja California Norte. Average rainfall totals are between 600 and 1,000 millimeters (23.6 and 39.4 in) in most of the major populated areas of the southern altiplano, including Mexico City and Guadalajara.

For example, if 30 of 50 members indicated greater than 1 cm rainfall during the next 24 h, the probability of exceeding 1 cm could be estimated to be 60%. The forecast would be considered reliable if, considering all the situations in the past when a 60% probability was forecast, on 60% of those occasions did the rainfall actually exceed 1 cm.
